It is an old issue but I could not find similar bug in JBS.
It is NOT a regression!

This issue is Solaris 11 specific. Not reproducible on Solaris 10.
This issue is JDK 1.5 specific. Not reproducible on other trains.

if I use -Dawt.toolkit=sun.awt.X11.XToolkit program can run.

Run slot:
http://aurora.ru.oracle.com/functional/faces/RunDetails.xhtml?names=483763.ute.st2-1

For example:
http://aurora-ds3.us.oracle.com:9502/runs%2F483763.ute.st2-1/results/ResultDir/X__O_copy_1/X__O.log

Output:
