Hello all,

I've upgraded Eclipse 3.7 to the latest software. I checked all that could be updated.

Now however, I keep getting the following popup:

index.php/fa/8003/0/

Exception (copied from the Eclipse .log):

!ENTRY org.eclipse.jface 4 2 2012-04-20 08:54:58.618
!MESSAGE Problems occurred when invoking code from plug-in: "org.eclipse.jface".

Note this appears twice in the log, thus the two NPEs in the popup.

Note, that I'm using JBoss Tools. When I edit any Java file a popup dialog appears on every save operation while the JBoss 7 server is running. It could hardly be more annoying to be honest!

What's wrong here? Can this be fixed? Who's responsible?

I cannot revert to the previous install, it fails with some error that some older repos aren't found or so.

Not sure who contributes the
com.sun.enterprise.jst.server.sunappsrv.actions but it sounds like WTP?

JFace only catches the exception and logs it.

Note, I'm also using the GlassFish plugins. It looks like

http://java.net/nonav/projects/glassfishplugins/lists/cvs/archive/2008-11/message/21

has reappeared. I wonder how this can happen...

How can I revert the plugin to a previous version in Eclipse?
