Build Identifier: 20110218-0911 org.eclipse.ui.internal.activities.Activity: fireActivityChanged() operates directly on the listener list and not on a copy of it. Therefore if a listener is removed during the activityChange() subsequent listener are skipped. I would suggest to make a temporary copy of the activityListener List and use it in the notification loop. Reproducible: Always Steps to Reproduce: 1. Add two IActivityListener to the same Activity (IActivity.addActivityListener) 2. Let the first listener remove itself from the activity when called by calling IActivity.removeActivityListener 3. Change the activity on which the two listener where added. Result: The first listener removes itself from IActivity and the second listener is not called.
