In my fairly huge workspace the Quick Type hierarchy (Cmd + T) occasionally performs really poor. Especially when building large hierarchies. What I noticed it that there is no way for a user to cancel/abort the command. The UI is blocked with a spinning wheel. Sometimes I notice a cancel button in the status line. However, that seems to go away after pressing ESC and/or switching to a different application (Cmd+tab). When switching back to Eclipse with Cmd+tab the wheel is still spinning and no way to cancel. Expected: ESC is always working to cancel/abort Cmd+T.

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.
