I don't see the problem with 1.3 on either solaris or NT
Whatever the cause of your problem its not reproducible with the test
case - once one fix is made.
I notice you aren't passing the JPEGEncodeParam parameter into the encode
method which would account for it not making a difference, but perhaps that
was an accident in distilling down your code into a test case.
