Tried following the steps at: http://dev.eclipse.org/viewcvs/index.cgi/%7Echeckout%7E/platform-vcm- home/docs/online/bugs-plugin/index.html to install the Bugzilla plugin. Got the following exception when pressing Finish and the Wizard did not close: eclipse.buildId=I200411091436 java.version=1.4.2_03 java.vendor=Sun Microsystems Inc.

I've checked that this works with M3 but in the latest integration build I too get this error trying to install a feature from an update site. Marking as blocker since you can't use update/install anymore. Regresssion from M3.
John, this class was changed recently. Do you know what is going on?
I recently updated IJobManager.addJobChangeListener/removeJobChangeListener to use the ListenerList class to fix thread safety problems. This class does not accept null listeners, which is a legitimate thing for us to be checking. The class InstallWizard.launchInBackground is removing a null listener. Moving to update.
*** Bug 78374 has been marked as a duplicate of this bug. ***
Fixed by checking for null listener before removeListener() . Also, check for null job before cancel().
