esmithbss: Just turned off my glassfish instance used for ruby debugging.  Switched tabs in Bottom right panel to second debugger instance running separate program.

Comment 9 Martin Krauskopf 2008-10-09 14:24:16 UTC 
*** Issue 148589 has been marked as a duplicate of this issue. ***
Comment 10 Martin Krauskopf 2008-10-10 12:08:35 UTC 
There are some problems. Likely synchronization issue. Evaluating.... relatively easy to reproduce. Hopefully in 6.5
time-frame.
Comment 11 Martin Krauskopf 2008-10-10 14:29:20 UTC 
Breakpoint management needs to be properly synchronized. Will do so in the intermediate library at debug-commons.
Increasing to P2 -> visibly affects management of multiple breakpoints at once.
Comment 12 Martin Krauskopf 2008-10-10 15:55:47 UTC 
Fixed. Changeset: #ddcd2254cbee

Commit message:
#148583: race condition in breakpoint management (fixed in the debug-commons-java)

debug-commons-java ChangeLog:
- Use logger per class to have more fine-grained logging
- Properly synchronize breakpoint management to prevent CME (cf.
  testRemovingBreakpointFromMultipleThreads)
- Be little bit more nicer to clients when trying to manage breakpoints
  when session is finished. (+ fixing typo)

Reopening - reproduced in NetBeans IDE 6.5 (Build 200811100001)

Comment 16 esmithbss 2008-11-21 21:11:27 UTC 
Looks like this one snuck back in somehow.

Log File from 6.5 FCS
Comment 18 Martin Krauskopf 2008-11-24 15:38:08 UTC 
From the log, as well as from the code, it looks like, that it is "just" WARNING-level message. Does it somehow break
debugger functionality or does NetBeans pops up dialog with the error?
Comment 19 esmithbss 2008-11-24 17:43:41 UTC 
Yes, this is popped up in the "An error has occurred" dialog that let's me file it as a bug.  It may be a warning, but
if it is, then there's a setting that is telling NB that it is severe enough to show me the dialog.
Comment 20 Martin Krauskopf 2008-11-25 08:23:20 UTC 
Ok, thanks. Will double-check that.

Otherwise does the debugger stop to works for you completely then? Or just one debugger session? Or the debugger works
as expected? Just to found out how serious the issue is.
Comment 21 Martin Krauskopf 2008-11-27 12:46:56 UTC 
I've added more checks to the intermediate library. Reopen, if you are able to reproduce in 7.0 dev build, thanks (you
will be notified about trunk integration here, when it is done).
