There are two problems here: problem 1: - ran target eclipse under debugger (also a 202a install, plus changes to org.eclipse.ui) - set breakpoint in Action.run() (actually it was in a new method run(Event), but this should reproduce it) - in Java perspective in target eclipse, hit Create a Java Project button on toolbar - breakpoint was hit (in WWinPluginAction(PluginAction).run(), so it was showing source for PluginAction.java). - stepped through it until it called the delegate (delegate.run(this)) - stack frame was added: OpenProjectWizardAction(AbstractOpenWizardAction).run(IAction) - source did not change: still showing PluginAction.java - Open On / Declaring Type or Receiving Type had no effect, either on this stack frame or previous one, but did on earlier ones problem 2: - tried clicking down in lower stack frames, in rapid succession to see if other frames were OK - got a "Failed to execute runnable" error dialog - log had: Log: Thu Oct 04 11:21:04 EDT 2001 1 org.eclipse.core.resources 4 Unhandled exception caught in event loop.

NOTES:
PRODUCT VERSION: 202a
I could not reproduce problem #1. Problem #2 was reproducable by rapidly clicking between stack frames that are from different compilation units (resulting in JavaEditors opening and closing rapidly). The failed runnable: Unhandled exception caught in event loop. Reason: Failed to execute runnable (java.lang.NullPointerException) java.lang.NullPointerException at org.eclipse.ui.texteditor.AbstractTextEditor.getCursorPosition(Abstra ctTextEditor.java:2172) at org.eclipse.ui.texteditor.AbstractTextEditor.updateStatusField(Abstra ctTextEditor.java:2150) at org.eclipse.ui.texteditor.AbstractTextEditor.handleCursorPositionChan ged(AbstractTextEditor.java:2130) at org.eclipse.ui.texteditor.AbstractTextEditor$5.run(AbstractTextEditor .java:779) at org.eclipse.swt.widgets.RunnableLock.run(RunnableLock.java:29) at org.eclipse.swt.widgets.Synchronizer.runAsyncMessages(Synchronizer.ja va:93) at org.eclipse.swt.widgets.Display.runAsyncMessages(Display.java:1345) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:1173) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java:781) at org.eclipse.ui.internal.Workbench.run(Workbench.java:764) at org.eclipse.core.internal.boot.InternalBootLoader.run(InternalBootLoa der.java:820) at org.eclipse.core.boot.BootLoader.run(BootLoader.java:285) at java.lang.reflect.Method.invoke(Native Method) at org.eclipse.core.launcher.Main.basicRun(Main.java:151) at org.eclipse.core.launcher.Main.run(Main.java:502) at org.eclipse.core.launcher.Main.main(Main.java:362) Looks like the AbstractTextEditor is attempting a runnable after it is disposed. Moving to Platform UI.
Kai, could you please take a look at this.
This is high priority for the debug team. It causes eclipse to crash in such a way that metadata corrupted and unrecoverable.
Introduced guard code for all async exec. Build > 20011204.
