Comment 1 Svata Dedic 2000-08-29 09:54:59 UTC 
Most probably caused by a race condition during initialization of
JavaDataObject.
Fixed in Dev-X builds.
Comment 2 Svata Dedic 2000-11-01 06:57:59 UTC 
Merged into Boston, too (9/29)
Comment 3 Jan Becicka 2001-02-22 14:07:41 UTC 
[010221_2] Verified
Comment 4 Quality Engineering 2003-07-01 13:15:47 UTC 
Resolved for 3.4.x or earlier, no new info since then -> closing.
