A user (Gilles Iachelini) just reported the following stack trace when selecting and opening all five views available under "Window->Show View->Other->Code Recommenders" at once. java.util.ConcurrentModificationException at java.util.ArrayList$Itr.checkForComodification(ArrayList.java:886) at java.util.ArrayList$Itr.next(ArrayList.java:836) at java.util.AbstractList.equals(AbstractList.java:521) at com.google.common.collect.AbstractMapBasedMultimap$WrappedCollection.equals(AbstractMapBasedMultimap.java:431) at com.google.common.base.Objects.equal(Objects.java:55) at com.google.common.collect.AbstractMapEntry.equals(AbstractMapEntry.java:49) at org.eclipse.jface.viewers.StructuredViewer.equals(StructuredViewer.java:727) at org.eclipse.jface.viewers.AbstractTableViewer.internalRefreshAll(AbstractTableViewer.java:710) at org.eclipse.jface.viewers.AbstractTableViewer.internalRefresh(AbstractTableViewer.java:650) at org.eclipse.jface.viewers.AbstractTableViewer.internalRefresh(AbstractTableViewer.java:637) at org.eclipse.jface.viewers.StructuredViewer$7.run(StructuredViewer.java:1508) at org.eclipse.jface.viewers.StructuredViewer.preservingSelection(StructuredViewer.java:1443) at org.eclipse.jface.viewers.StructuredViewer.preservingSelection(StructuredViewer.java:1404) at org.eclipse.jface.viewers.StructuredViewer.refresh(StructuredViewer.java:1506) at org.eclipse.jface.viewers.ColumnViewer.refresh(ColumnViewer.java:544) at org.eclipse.jface.viewers.StructuredViewer.refresh(StructuredViewer.java:1465) at org.eclipse.recommenders.internal.models.rcp.ProjectCoordinatesView.refreshTableUI(ProjectCoordinatesView.java:527) at org.eclipse.recommenders.internal.models.rcp.ProjectCoordinatesView.access$8(ProjectCoordinatesView.java:523) at org.eclipse.recommenders.internal.models.rcp.ProjectCoordinatesView$10.runInUIThread(ProjectCoordinatesView.java:517) at org.eclipse.ui.progress.UIJob$1.run(UIJob.java:95) at org.eclipse.swt.widgets.RunnableLock.run(RunnableLock.java:35) at org.eclipse.swt.widgets.Synchronizer.runAsyncMessages(Synchronizer.java:135) at org.eclipse.swt.widgets.Display.runAsyncMessages(Display.java:3976) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3653) at org.eclipse.e4.ui.internal.workbench.swt.PartRenderingEngine$9.run(PartRenderingEngine.java:1113) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:332) at org.eclipse.e4.ui.internal.workbench.swt.PartRenderingEngine.run(PartRenderingEngine.java:997) at org.eclipse.e4.ui.internal.workbench.E4Workbench.createAndRunUI(E4Workbench.java:140) at org.eclipse.ui.internal.Workbench$5.run(Workbench.java:611) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:332) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:567) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:150) at org.eclipse.ui.internal.ide.application.IDEApplication.start(IDEApplication.java:124) at org.eclipse.equinox.internal.app.EclipseAppHandle.run(EclipseAppHandle.java:196) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.runApplication(EclipseAppLauncher.java:110) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.start(EclipseAppLauncher.java:79) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:354) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:181) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:483) at org.eclipse.equinox.launcher.Main.invokeFramework(Main.java:636) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:591) at org.eclipse.equinox.launcher.Main.run(Main.java:1450)
I tried different things to reproduce this bug but without success. Did we already fix it somewhere else? Does this bug occurs also with the newest version of Code Recommenders?
(In reply to Olav Lenz from comment #1) > I tried different things to reproduce this bug but without success. > > Did we already fix it somewhere else? > Does this bug occurs also with the newest version of Code Recommenders? Hi Olav, what I did was the following: I downloaded and installed the latest CR Version ("latest" in the sense of end of march). After restarting eclipse I openend the Windows->Views->... Dialog and selected all of the CR relevant views and openend them. Maybe, just maybe, it depends on the current selection which might influence the content of one or another view. Are there any shared ressources between the ProjectCoordinatesView and any other view?
Not reproducible (anymore).
Closing for 2.1
