using 3.1M2 on centrino 1.6Ghz notebook when completing (in-type), what seems to be all jar files in classpath is read 20-2000(!) times -> cpu goes 100% for 1 minute (using sysinternals filemon, javaw is the guilty, not virusscanners)¨ i dont expect plugins (ia use some) to be the problem, this is core functionality? went back to 3.0.1, no problems... i'll be happy to help w. debug info /aksel
i'll take 'using 3.0.1 wo. problems' very much back... same problem :( /Aksel
Pls provide steps to reproduce. Also thread dumps are most likely a good indication as well (launch Eclipse with console open, and press ctrl-pause to get VM to dump activity).
reproduce: - open eclipse - open type with an attribute - try to 'complete' any methods on that attribute (almost always works for me, but it has turned into this behaviour, not always been so...) evidence of filereading: try to install (worlds best freeware) filemon from sysinternals.com and see how all jar files are pounded - (I could include this log although it only states that javaw reads some jar files up to 2000 times in a row within seconds) maybe if this is expected behaviour, it is only my hdd which is about to fail (again)? starting eclipse with 'eclipse -vm h:\tools\j2sdk-se\1.4.2_03\jre\bin\java.exe -vmargs -Xmx256m' I have auto build off, plugins: - xmlbuddy - jigloo (ui editor) - enerjy profilers (auto start turned off, never uses) - findbugs -

*** Bug 76747 has been marked as a duplicate of this bug. ***
Aksel, do you still have the problem using 3.1 M4 (to be out at the en dof the week) ?
hi for a long time, the 'forever' symptome seemed gone, but yesterday, i worked on a 500+ file project and nearly every operation (not just completion, but maybe ast related tasks such as follow link to (f3), find ancestors (ctrl-t) took forever. starting filemon from sysinternals produced a near similar result as previously, but i am not sure that this is the same problem. every jar file is read thousands and thousands of times - maybe this is because of low mem? (i have 1 gb, but it could still be exhausted - i didnt check)) the javaw process made over 50 millions (!) read accesses, mostly to jar files. the process explorer (sysinternals) showed which handles were held by eclipse and this revealed about 55 jar files (all plugins etc. included), the 'core' build classpath of the project was 12 jar files and two source folders. common to the file accesses was very small reads (20-100 bytes) but many, here is an example from filemon: 1 15:34:19 javaw.exe:2692 READ H:\cws-flex-build\nightly\cws- flex\dev\build\lib\cws-flex.jar SUCCESS Offset: 3047460

no, it is not mem-exhaustion, still got 400 mb free i can reproduce now with ease it may be worth to mention that the classpath entries is located on a pgp- drive, but i cant see why this should slow down this much - file operations could generally be slower but it still doesn't explain the millions af reads /aksel
Hi - I see what appears to be the same problem, or a related problem, but in a different place. Here's what I do: Start Eclipse, go to Java Browsing perspective, click on my project in the Projects view. Eclipse then goes busy for a few minutes. Once it completes whatever it's doing, things work normally. Selecting e.g. a source folder in my project, then selecting the project itself again, causes the problem to happen again. If I reproduce the problem in a Runtime Workbench, and pause it in the debugger at intervals, I see that Eclipse is doing something to the jars in my project's lib (there are 70+ jars in there). From the stack trace, I would guess that it is rebuilding the contents of the Packages view. Perhaps some cache or index is not being saved? Here is one such stack trace (apologies for messy pasting): Thread [main] (Suspended) ZipFile.getNextEntry(long, int) line: not available [native method] ZipFile.access$400(long, int) line: 26 ZipFile$2.nextElement() line: 313 [local variables unavailable] JarPackageFragmentRoot.computeChildren(OpenableElementInfo, Map) line: 86 JarPackageFragmentRoot(PackageFragmentRoot).buildStructure(OpenableElementInfo, IProgressMonitor, Map, IResource) line: 173 JarPackageFragmentRoot(Openable).generateInfos(Object, HashMap, IProgressMonitor) line: 203 JarPackageFragmentRoot(JavaElement).openWhenClosed(Object, IProgressMonitor) line: 547 JarPackageFragmentRoot(JavaElement).getElementInfo(IProgressMonitor) line: 291 JarPackageFragmentRoot(JavaElement).getElementInfo() line: 277 JarPackageFragmentRoot(JavaElement).getChildren() line: 232 JarPackageFragment(PackageFragment).hasSubpackages() line: 355 EmptyInnerPackageFilter.select(Viewer, Object, Object) line: 35 PackagesViewTableViewer(StructuredViewer).filter(Object[]) line: 585 PackagesViewTableViewer.selectLogicalPackage(LogicalPackage) line: 83 PackagesViewTableViewer.getFilteredChildren(Object) line: 70 PackagesViewTableViewer(StructuredViewer).getSortedChildren(Object) line: 823 PackagesViewTableViewer(TableViewer).internalRefresh(Object, boolean) line: 725 PackagesViewTableViewer(TableViewer).internalRefresh(Object) line: 706 PackagesViewTableViewer.internalRefresh(Object) line: 105 StructuredViewer$7.run() line: 1172 PackagesViewTableViewer(StructuredViewer).preservingSelection(Runnable) line: 1109 PackagesViewTableViewer(StructuredViewer).refresh(Object) line: 1170 PackagesViewTableViewer(StructuredViewer).refresh() line: 1129 PackagesViewTableViewer(TableViewer).inputChanged(Object, Object) line: 667 PackagesViewTableViewer(ContentViewer).setInput(Object) line: 248 PackagesViewTableViewer(StructuredViewer).setInput(Object) line: 1314 PackageViewerWrapper.setViewerInput(Object) line: 307 PackagesView.setViewerWrapperInput(Object) line: 340 PackagesView.setInput(Object) line: 335 PackagesView(JavaBrowsingPart).adjustInputAndSetSelection(Object) line: 1003 PackagesView.adjustInputAndSetSelection(Object) line: 411 PackagesView(JavaBrowsingPart).selectionChanged(IWorkbenchPart, ISelection) line: 754 AbstractSelectionService$4.run() line: 182 InternalPlatform.run(ISafeRunnable) line: 1044 Platform.run(ISafeRunnable) line: 747 PageSelectionService(AbstractSelectionService).firePostSelection(IWorkbenchPart, ISelection) line: 180 AbstractSelectionService$2.selectionChanged(SelectionChangedEvent) line: 75 StructuredViewer$3.run() line: 681 InternalPlatform.run(ISafeRunnable) line: 1044 Platform.run(ISafeRunnable) line: 747 ProblemTreeViewer(StructuredViewer).firePostSelectionChanged(SelectionChangedEvent) line: 679 ProblemTreeViewer(StructuredViewer).handlePostSelect(SelectionEvent) line: 950 StructuredViewer$5.widgetSelected(SelectionEvent) line: 970 OpenStrategy.firePostSelectionEvent(SelectionEvent) line: 231 OpenStrategy.access$4(OpenStrategy, SelectionEvent) line: 226 OpenStrategy$3.run() line: 392 RunnableLock.run() line: 35 UISynchronizer(Synchronizer).runAsyncMessages(boolean) line: 118 Display.runAsyncMessages(boolean) line: 2780 Display.readAndDispatch() line: 2451 Workbench.runEventLoop(Window$IExceptionHandler, Display) line: 1569 Workbench.runUI() line: 1540 Workbench.createAndRunWorkbench(Display, WorkbenchAdvisor) line: 285 PlatformUI.createAndRunWorkbench(Display, WorkbenchAdvisor) line: 144 IDEApplication.run(Object) line: 102 PlatformActivator$1.run(Object) line: 220 EclipseStarter.run(Object) line: 273 EclipseStarter.run(String[], Runnable) line: 129 NativeMethodAccessorImpl.invoke0(Method, Object, Object[]) line: not available [native method] NativeMethodAccessorImpl.invoke(Object, Object[]) line: 39 DelegatingMethodAccessorImpl.invoke(Object, Object[]) line: 25 Method.invoke(Object, Object[]) line: 324 Main.basicRun(String[]) line: 185 Main.run(String[]) line: 710 Main.main(String[]) line: 694 The ZipFile instance at the top refers to one of the jars in my project's lib directory. Pausing later on gives a similar trace with a different jar, and so on. Hope this helps. I'll try to investigate more but I confess this is my first time in the PDE/runtime-workbench side of things. Cheers Richard
Doh - sorry that was with 3.1M4, no extra plugins. Previously with 3.0.1 I had not seen the problem.
After some investigation my suspicions lie in and around JavaElement.openWhenClosed() : I think that ElementInfos for JarPackageFragments/JarPackageFragmentRoots (built up during this method's use of the JavaModelManager's thread-local 'temporary cache') are not always making it into the 'main' cache. But, this might just be my lack of understanding. I'll try to figure out how to actually change the code locally instead of just debugging it from a source attachment, so I can test my theory. Jumping in at the deep end like this is pretty mind-blowing but it's fun ;)
Aksel - Inside comment 6 i can see that cws-flex.jar is on H drive. Is it a network drive ? If it is a network drive, did you observe the same problem on a local drive ? If it is possible, could you try to reproduce the problem on a local (and not pgp) drive ? I aks this question to know if the problem is caused by the nature of this drive or not.
The first problem seems to be the same as bug 86579. Tom, could you confirm that ? The second problem (comment 8) seems to be a little bit different.
Hi there. I wrote comment #8 and I can well believe that is, in fact, a separate problem. FYI I've been unable to replicate my problem in M5a - so you should probably ignore my comments on this bug. Good luck ;)

oh, i just reproduced on M5a thanks! /aksel
(In reply to comment #12) > The first problem seems to be the same as bug 86579. > > Tom, could you confirm that ? Looking at the thread dump this is almost certainly a dup of bug 86579. > The second problem (comment 8) seems to be a little bit different. Agree, this sounds more like an IO issue. Doesn't have anything to do with code assist anyway.

I got this issue on eclipse 3.1 when I'm trying to open a java package view in our project, the eclipse seems freezed (except the project's java files are very few), I have to pause the running and I got a stack trace like this: JarPackageFragmentRootInfo(PackageFragmentRootInfo).<init>() line: 50 JarPackageFragmentRootInfo.<init>() line: 16 JarPackageFragmentRoot.createElementInfo() line: 148 JarPackageFragment.generateInfos(Object, HashMap, IProgressMonitor) line: 113 JarPackageFragment(JavaElement).openWhenClosed(Object, IProgressMonitor) line: 488 JarPackageFragment(JavaElement).getElementInfo(IProgressMonitor) line: 232 JarPackageFragment(JavaElement).getElementInfo() line: 218 JarPackageFragment(JavaElement).getChildren() line: 173 JarPackageFragment(JavaElement).getChildrenOfType(int) line: 187 JarPackageFragment.getClassFiles() line: 120 NameLookup.seekTypesInBinaryPackage(String, IPackageFragment, boolean, int, IJavaElementRequestor) line: 793 NameLookup.seekTypes(String, IPackageFragment, boolean, int, IJavaElementRequestor) line: 769 NameLookup.findType(String, IPackageFragment, boolean, int) line: 542 NameLookup.findType(String, String, boolean, int) line: 501 NameLookup.findType(String, boolean, int) line: 633 JavaProject.findType(String, WorkingCopyOwner) line: 1141 JavaProject.findType(String) line: 1113 JavaProject.findType(String, WorkingCopyOwner) line: 1149 JavaProject.findType(String) line: 1113 JavaClassUtils.getQualifiedTypeName(IType, String) line: 537 JavaClassUtils.getQualifiedTypeNameInTypeHierarchy(IType, String) line: 470 JavaBeanUtils.getMethodWithSameParamters(IMethod[], Map, IMethod, String, String []) line: 708 JavaBeanUtils.getBeanProperties(IType, IMethod[]) line: 795 ManagedBeanTreeItem.addPropertyItems(IType, IMethod[], TreeParent, List) line: 539 ManagedBeanTreeItem.getClassInformation(TreeParent, String, ManagedBeanTypeImpl) line: 522 ManagedBeanTreeItem.getBeanInformation(TreeParent) line: 442 ManagedBeanTreeItem.hasChildren() line: 252 ScopeContentProvider(ManagedBeanContentProvider).hasChildren(Object) line: 133 DataBindingsContentProvider.hasChildren(Object) line: 208 DataBindingViewer(AbstractTreeViewer).isExpandable(Object) line: 1378 DataBindingViewer(AbstractTreeViewer).updatePlus(Item, Object) line: 1845 DataBindingViewer(AbstractTreeViewer).createTreeItem(Widget, Object, int) line: 536 AbstractTreeViewer$1.run() line: 514 BusyIndicator.showWhile(Display, Runnable) line: 69 DataBindingViewer(AbstractTreeViewer).createChildren(Widget) line: 494 DataBindingViewer(AbstractTreeViewer).handleTreeExpand(TreeEvent) line: 948 AbstractTreeViewer$4.treeExpanded(TreeEvent) line: 959 TypedListener.handleEvent(Event) line: 180 EventTable.sendEvent(Event) line: 66 Tree(Widget).sendEvent(Event) line: 843 Tree(Widget).sendEvent(int, Event, boolean) line: 867 Tree(Widget).sendEvent(int, Event) line: 852 Tree.wmNotifyChild(int, int) line: 3708 Composite(Control).WM_NOTIFY(int, int) line: 3568 Composite.WM_NOTIFY(int, int) line: 1035 Composite(Control).windowProc(int, int, int, int) line: 3089 Display.windowProc(int, int, int, int) line: 3706 OS.CallWindowProcW(int, int, int, int, int) line: not available [native method] OS.CallWindowProc(int, int, int, int, int) line: 1580 Tree.callWindowProc(int, int, int, int) line: 219 Tree.WM_LBUTTONDOWN(int, int) line: 2815 Tree(Control).windowProc(int, int, int, int) line: 3071 Tree.windowProc(int, int, int, int) line: 2391 Display.windowProc(int, int, int, int) line: 3706 OS.DispatchMessageW(MSG) line: not available [native method] OS.DispatchMessage(MSG) line: 1656 Display.readAndDispatch() line: 2711 Workbench.runEventLoop(Window$IExceptionHandler, Display) line: 1699 Workbench.runUI() line: 1663 Workbench.createAndRunWorkbench(Display, WorkbenchAdvisor) line: 367 PlatformUI.createAndRunWorkbench(Display, WorkbenchAdvisor) line: 143 IDEApplication.run(Object) line: 103 PlatformActivator$1.run(Object) line: 226 EclipseStarter.run(Object) line: 376 EclipseStarter.run(String[], Runnable) line: 163 NativeMethodAccessorImpl.invoke0(Method, Object, Object[]) line: not available [native method] NativeMethodAccessorImpl.invoke(Object, Object[]) line: 39 DelegatingMethodAccessorImpl.invoke(Object, Object[]) line: 25 Method.invoke(Object, Object[]) line: 324 Main.invokeFramework(String[], URL[]) line: 334 Main.basicRun(String[]) line: 278 Main.run(String[]) line: 973 Main.main(String[]) line: 948 The problem is on eclipse ver 3.0, I didn't encounter this problem. And the stange is my colleagues don't have this problem on 3.1. But on my machine each time I try to open the viewer I can reproduce this problem. I see a similiar bug report that is 75153. But this happens to 3.1 release, so what's the conclusion of this performance issue, machine, jdk, or eclipse itself, why 3.0 has no problem, only 3.1 ? Anyone can help?
