A DESCRIPTION OF THE PROBLEM :
When a JWindow is created, the size can never be changed.

This is not a problem on MS Windows, or on Solaris with java 1.4.2, but on Solaris (both x86 and SPARC) with java 1.5, it is a problem. I reproduce the problem with 1.5.0_01 and 1.5.0_04 on x86 Solaris 10, and 1.5.0_01 on SPARC Solaris 10. The problem does NOT occur with 1.4.2_06 on x86 Solaris 10.




STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Test case:
Compile and run the program provided in "Source Code" below, jwindowbug.JWindowBug. You'll get a small frame with a button that says "Open JWindow". Clicking the button brings up a JWindow on top of the frame. Every second, the JWindow's size will be changed, so you should see the window growing and then shrinking back to the original size. After 20 seconds, the JWindow will close.

On Windows with JRE 1.4 or 1.5,, or on Solaris with a 1.4 VM, this works fine. On Solaris with a 1.5 VM, the JWindow never changes size.



EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The JWindow should change once per second for 20 seconds, then close. This is what happens on Windows or with JRE 1.4 on Solaris.
ACTUAL -
The JWindow never changes size. The size it is when it is created is the size it stays.

REPRODUCIBILITY :
This bug can be reproduced always.
