Description Svata Dedic 2000-12-05 11:06:06 UTC 
Dev-21 build:
I tried to disable java module; my IDE was cut down to the bare functionality so
only appisupport needed to be disabled too. Please see attached ide.log

Comment 2 Jaroslav Tulach 2001-02-02 10:15:59 UTC 
Should be fixed, all code that is accessing DataObjectPool.map seems to be
synchronized.
Comment 3 Martin Ryzl 2001-02-09 11:32:59 UTC 
Occured again in Pilsen build 010205_2. It happens randomly, usually when I
install/uninstall module for testing.
