Comment 1 Jan Zajicek 2002-04-10 08:23:49 UTC

First exception is probably issue in jdk. Which version of jdk are you
using? The second one can be explained in form module.

Comment 2 Tomas Pavek 2002-04-15 13:49:36 UTC

The exception looks suspiciously similar to that from 
issue 21692. However, I still have no idea how it could 
happen...

*** This issue has been marked as a duplicate of 21692 ***

Comment 3 Quality Engineering 2003-06-30 18:21:24 UTC

Resolved for 3.3.x or earlier, no new info since then -> closing.

Comment 4 Quality Engineering 2003-06-30 18:27:08 UTC

Resolved for 3.3.x or earlier, no new info since then -> closing.
