eclipse.buildId=I20110225-1300

- had only the Java perspective open
- edited a Java file
- set a breakpoint
- from the context menu Debug As -> Java Application
- didn't switch perspectives, got the following error instead

Work-around is to manually open the Debug perspective.

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.
