Description Jan Lahoda 2003-04-10 14:06:39 UTC 
Nevada 030408, JDK1.4.1_02, MDI.
1. Download attached test case.
2. Mount it in the IDE (no package).
3. Start debugging of this class (Debug/Start
Session/Run in Debugger) (do not set any
breakpoints, the testcase is an infinite loop).
4. Start it again. Choose "Start New Session".
5. In the sessions view, choose "Finish" on the
second session. Attached NullPointerException will
occur.

Note: Although the steps to reproduce run the same
class twice, it is not necessary. The same problem
occurs when debugging two different applications,
even if one or both of them are "Attached".

ms that this problem disappeared.
