A DESCRIPTION OF THE PROBLEM :
If the setDefaultLookAndFeelDecorated(true) method has been called on JFrame and/or JDialog the resize becomes highly erratic. The symptoms are less severe when resized from the lower-right corner, but are most pronounced when re-sized with the upper-left corner. The window doesn't follow the mouse and will randomly change size as the mouse is moved. This problem is present on the Metal Look and Feel but I haven't tried it on any others.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Create a JFrame window after calling JFrame.setDefaultLookAndFeelDecorated(true). Then attempt to resize the window using the corners.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The window should resize smothly and the corner being used to resize should follow the mouse pointer.
ACTUAL -
The window resizes erratically.

REPRODUCIBILITY :
This bug can be reproduced always.
