Description Jan Lahoda 2002-06-27 18:48:59 UTC 
build 200206260100, JDK1.4fcs, MDI.
1. Start IDE from a brand new user directory
2. Do *not* close the welcome screen.
3. Open ClockFrame example (in editing mode).
4. Start debugger (F7) on it.
5. You are switched to Debugging workspace. The
welcome screen undocked outside the MDI frame
(!!!) (this happens at least sometimes).
6. Close the editor, and if the welcome screen is
undocked, close it too.
7. Switch back to editing workspace. The welcome
screen is always open (even in case it was in step
5 docked in editor, and you close the editor).
8. Open the ClockFrame (in editing mode) again.
9. Stop the debugger.
10. Start it again (F7).
11. Two ArrayIndexOutOfBoundsException exceptions
occur (attached is 
whole IDE log).

I reproduced it also with not new userdir, and it
seems to be (at least partialy) related to welcome
screen.

Created attachment 6474 [details]
The IDE log (contains the exceptions).
Comment 2 Peter Zavadsky 2002-06-28 08:44:35 UTC 
It seems it's either a race condition (JTabbedPane#getSelectedIndex
and remove method shouldn't produce AIIOOBE in single thread model) or
a bug in JTabbedPane. The first seems to be the case. Will investigate.
Comment 3 Peter Zavadsky 2002-06-28 09:43:48 UTC 
I reproduced it on jdk1.4.0, but not on jdk1.4.1.
Comment 4 Peter Zavadsky 2002-06-28 10:41:49 UTC 
Well it was only once I reproduced it, so I can't figure out the
problem. Anyway also some strange effect saw once, also the closed
ClockFrame when switched back to Editing was shown as a tab but the
component was not visible. All on jdk1.4.0.
Comment 5 Peter Zavadsky 2002-06-28 12:19:03 UTC 
Can't reprocuce (only the one occurence) -> decreasing the priority.
Please let me know if you are able reproduce it on your machine, I'd
like to debug there in that case.
Comment 6 Peter Zavadsky 2002-07-08 10:17:53 UTC 
Now the welcome window doesn't act that way anymore (Marek fixed those
problems with it). Closing this as worksforme, the issue could be
related to the welcome window problems.
Comment 7 Quality Engineering 2003-07-01 15:54:39 UTC 
Resolved for 3.4.x or earlier, no new info since then -> verified.
Comment 8 Quality Engineering 2003-07-01 16:41:22 UTC 
Resolved for 3.4.x or earlier, no new info since then -> closing.
