I20071204-1547 I took a stacktrace while the UI thread was blocked for more than 10 seconds (could have been due to a garbage collection, I don't really know what caused the blocking). However, I saw that the TypesView was updating its contents, although I was in the Java perspective, and the Types view was not even open in the current perspective. Views should not update their contents while they are not visible.

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. -- The automated Eclipse Genie.
Still an issue in 4.11 M1.
