Hi, I am using Eclipse 3 M9 build I200405211200 and I have problems with
connecting swt with swing. 
I wrote a plugin for eclipse with swing components,
most of the time it works fine but there seem to be errors in the event handling
of the SWT_AWT class, 
the added eventlistener are not removed on dispose of the AWT Frame, 
so eclipse continues sending events to the frame, this produce errors like this:

java.lang.NullPointerException
	at org.eclipse.ui.internal.EditorManager$7.run(EditorManager.java:801)
	at
org.eclipse.core.internal.runtime.InternalPlatform.run(InternalPlatform.java:608)
	at org.eclipse.core.runtime.Platform.run(Platform.java:758)
	at org.eclipse.ui.internal.EditorManager.busyRestoreEditor(EditorManager.java:775)
	at org.eclipse.ui.internal.EditorManager$6.run(EditorManager.java:768)
	(...)

!MESSAGE Unhandled event loop exception

	at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:82)
	at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:796)

	at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:82)
	at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:796)
	(...)

and sometimes eclipse crashes completely. With Eclipse version 3.1 M1 the errors
dont occur in the error log, 
but eclipse sometimes crashes too.

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet.

If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.
