Description Emerson Cargnin CLA 2004-02-03 16:43:07 EST 
I just set eclipse to not ask when exiting and got a null pointer at the command
line and the following stacktrace at .log file. I couldn't reproduce the error...

Comment 1 Dani Megert CLA 2004-02-06 02:27:40 EST 
Which build?
Comment 2 Dani Megert CLA 2004-02-06 09:15:34 EST 
Cannot reproduce either. This looks like a side-effect of another bug: when
shutting down we first unregister the listeners and then null-out the fields.

We need the build Id in order to map the line number to the code where the NPE
happens.
Comment 3 Dani Megert CLA 2004-08-29 16:56:38 EDT 
waiting for answer
Comment 4 Dani Megert CLA 2007-06-22 09:59:06 EDT 
Get rid of deprecated state.
