I'm using eclipse 3.0.0 Build 200405211200 When in the Navigator view of my project and I right-click on a .java file, the pop-up menu sometimes hangs. This is not consistent, but when it does hang, the entire eclipse application is frozen and can only be halted via task manager cancel of task. I wish it could be recreated at will, but it cannot be. The next time it happens, is there something specific I should do to assist in debugging this problem? By the way, the copyright for Eclipse Help/About is dated 2003 -- should it be 2004?
Created attachment 11296 [details] Picture of UI hung Picture of hung UI.
Copyright messages will be changing as we get closer to releasing Eclipse 3.0.
To debug hangs/deadlocks, try running with -vm ...\jre\bin\java (instead of javaw, which is the default). This gives you a console window. Edit its properties (window menu > Properties) to have a bigger screen buffer size, e.g. width 138, height 3000. When the hang occurs, press Ctrl+Break in the console window. This gives a dump of all threads. Attach the entire result here (to copy the buffer: window menu > Edit > Select All, Enter). Some other questions: Do you have any other plug-ins installed, other than what comes with the Eclipse SDK? Do you ever edit your source files outside of Eclipse?
I have com.sysdeo.eclipse.tomcat_3.0.0.alpha1 plugin. I do edit JSP files in DreamWeaver. I do not edit JAVA source outside of eclipse. I have done WinCvs updates of the project, though. Perhaps WinCvs is what causes it. It does seem to correlate with the Team item of the Navigator pull-down. At any rate, I will run in console mode until it occurs again and post the dump here.
Okay. It happened with console on. I caused it by selecting a java file in Navigater perspective, right-clicked, choose Replace With->Latest from Branch myCvsName, and clicked OK to the Confirm Overwrite dialog. Ok so far; that is, it replaced it, and the > sign was removed from the Navigator view indicating that the file no longer differs from CVS branch. Then I right-clicked the same file and moved the mouse down a few entries and it froze. I did not do a deliberate Refresh after replacing from CVS. I do not have Project->Build Automatically checked. I tried to recreate it using different files after bringing Eclipse down and back up, but was unable to do so. After doing the Ctl-Break on the console after initial freeze-up, it seemed to free up.

Created attachment 11503 [details] Sorry -- here is the dump ATTACHED.
The only thread doing anything interesting here is the UI thread (main), and it is sleeping! This is in the Java model, but is triggered from the enablement expression for Debug's Run action. Moving to Debug for consideration.
Note that the "Referenced part does not exist yet" lines at the beginning are unrelated. It's a known problem with the Sync perspective.
Philippe/Jerome, it looks like our "applet property tester" is causing the java model to compute a type hierarchy, which is sleeping. Do you know why the type hierarchy would be sleeping (see the main thread)?
The hierarchy would be sleeping if there are jobs in the index queue. However the Java indexing thread is sleeping as well, which indicates there are no jobs to process. This sounds to me like a VM problem. Jerry I see you're using a quite old VM (JDK 1.4.1_02-b06). Could you please try with a more recent one (like JDK 1.4.2_04-b05) ?
Upgraded to java.runtime.version=1.4.2_04-b05. I'll see what happens and keep this posted.
Happened again. This time, I did no CVS at all. Seemingly random hang. I right-clicked on a java member and then moused down to Run and it hung. I had to terminate Eclpse this time (the last time, the Ctl-Break on console seemed to free it). Here is the dump (I will attach it, too): Full thread dump Java HotSpot(TM) Client VM (1.4.2_04-b05 mixed mode): "Worker-11" daemon prio=5 tid=0x188fc3f0 nid=0x9dc in Object.wait() [1a96f000..1a96fd88] at java.lang.Object.wait(Native Method) at org.eclipse.core.internal.jobs.WorkerPool.sleep(WorkerPool.java:209) -

Created attachment 11662 [details] Another dump for 07Jun2004
The applet launch shortcut is computing a type hierarchy, which appears to be sleeping.
Adopting. Looks like same bug as bug 65680
*** Bug 65680 has been marked as a duplicate of this bug. ***
Suspecting the index manager to remain in disabled state forever. Disabling pattern is: (A) boolean wasEnabled = isEnabled(); try { disable(); } finally { if (wasEnabled) (B) enable(); } So if 2 threads are competing, A1-A2-B1-B2 would leave us inconsistent.
Changed index manager to use a counter instead of a boolean. This counter is incremented in enable() and decremented in disable(). The disabling pattern is now: try { disable(); } finally { enable(); }
Created attachment 11805 [details] Happen again 09Jun2004 -- attached. Looks like this has been addressed, but ataching another dump as it happened again. Disregard if superfluous. Thank you so much working on this so quickly.

Created attachment 11936 [details] Dump showing Navigator hang in Build id: 200406110010 I have the newest version (build notes say this bug addressed). Hang occurred again. Dump attached. Version: 3.0.0 Build id: 200406110010
Sorry -- should have reopened before attaching dump.
Then I will need steps to reproduce the problem. At least can you please do the following ? 1. Add a .options file (say in c:\temp\.options) with the following content: # Turn on debug tracing for org.eclipse.jdt.core plugin org.eclipse.jdt.core/debug=true # Reports background indexer activity: indexing, saving index file, index queries org.eclipse.jdt.core/debug/indexmanager=true 2. Start eclipse with the following command line: eclipse.exe -vm <path to your jdk>\jre\bin\java.exe -debug c:\temp\.options 3. This opens a DOS console 4. Increase the Screen Buffer Size of the DOS console: Width=200 Height=9999 5. When you get the problem, attach the trace that is printed in the DOS console. Thanks.
Created attachment 11945 [details] Here it is as requested Full degug version of problem as requested.
Thanks Jerry. One more question: when it hangs, does the tracing stop, or do you get infinite 'java.util.zip.ZipException: Access is denied' ?
It was looping as I was copying the text. When I did the DOS Edit->Select All, it stopped, and when I pressed enter to copy the text, it started again. It did free up (after a minute or so); that is, I did not have to Ctl+Alt+Delete/task manager force it down. I never trust it after this happens, so I close Eclipse and start over.
OK, then you must have 'C:/Documents and Settings/bjal1/eclipse/jakarta-tomcat- 4.0.6' in your .classpath as a lib entry. This is not supported. Removing this entry should solve your problem.
Done. We'll see what happpens. Since I have this project defined as a Tomcat project, using com.sysdeo.eclipse.tomcat_3.0.0.alpha1, if this fixes it, I'll contact Sysdeco and let them know they have an issue by defining this variable automatically.

Created attachment 12024 [details] Warning shown for TOMCAT_PATH Ironically, Eclipse did give me a warning about TomCat (see attached sreen shot), but I followed some advice on a post somewhere, and was lead to believe that this warning was normal (even expected). The hang has not occurred since removing the "TOMCAT_HOME - C:\Documents..." line from the Project->Properties->Java Build Path->Libraries dialog. After removing this line, the warning (shown on screen shot) also disappeared. Thanks again for all of the help provided. It is greatly appreciated! I will definately contact Sysdeo and have them take a look at this post.
Glad I could help. We should however prevents this scenario from happening.
If we don't take this fix, then some clients may not notice they are constructing invalid classpaths (using external class folders, which are illegal). When such an ill-formed CP is constructed, offending entries are usually ignored from our code (i.e. when building, java model doesn't show it), but can induce a very long recursion inside our search index support (which almost seems an infinite loop, but is just very slow). Workaround is for client to fixup the classpath manually; but they have no clear indication of the problem, and have to guess based on symptoms. If we fix it, the only consequence is that IJavaProject#getResolvedClasspath (...) will now filter out these offending entries (which shouldn't have been exposed from day 1). This impacts JDT launching support, as it used to tolerate this mode of operation. So even though we did forbide external class folders (in spec, but not in validation code), runtime was tolerating these to be part of a runtime classpath. Workaround for clients would be to add arbitrary entries on runtime classpath if they did really want them; as these would no longer be made available by default (using JDT Core #getResolvedClasspath() API). The raw classpath would still continue to answer these. Darin - any thoughts ? are you supporting this change ?
CC'ing John as we did discuss this problem together.
We use "getRawClasspath()" when expanding a projects default runtime classpath, so this should have no ill effect on launching.
Released proposed patch and regression test.
