Comment 22 pratham_vishnu 2007-12-20 07:41:16 UTC

I have installed netbeans 6.0 on solaris 10 x86 with jdk1.6.0 and this error still persists.

Comment 23 Max Sauer 2007-12-20 09:30:19 UTC

Note this should be fixed in JDKs 7(b09), 6u2(b02). Please update your JDK to the latest version of JDK6, it should
help. If the problem persists, the JDK bug should be reopened, not this issue. Thanks.
