Comment 2 Jan Lahoda 2007-11-01 07:58:52 UTC 
Two separate problems here, IMO:
-scanning of openide/util/test/unit/src forever - I was not able to reproduce so far, but I will keep trying.
-parsing in the AWT - the callers of JavaSource.runUserActionTask need to do something about this, this cannot be solved
in the Java infrastructure. In this case it is:
org.netbeans.modules.j2ee.ejbcore._RetoucheUtil.getJavaClassFromNode(_RetoucheUtil.java:145)
org.netbeans.modules.j2ee.ejbcore.ui.logicalview.ejb.action.EJBActionGroup.enable(EJBActionGroup.java:125)
org.openide.util.actions.NodeAction$DelegateAction.resultChanged(NodeAction.java:611)

As Honza described above this issue has two problems:
1) The livelock
2) The AWT call to infrastructure (not so important) and outside of java editor (j2ee)
We will use this issue for the first problem.

Unfortunately I am not able to reproduce it either, I will attach the patched javac-impl.jar can you try to reproduce it
using this patched javac-impl.jar? It will generate debug messages we can use to find out what happens.

Comment 6 Tomas Zezula 2007-11-01 13:40:09 UTC 
Tonda had the version of openide/util with the broken source causing this bug (reproduceable case).

Fixed.
Checking in javac-impl.jar;
