A DESCRIPTION OF THE PROBLEM :
For some reasone the default height of a JPasswordField is larger than than for a JTextField, at least with the Windows LaF. This makes simple forms containing  simple username + password entry fields to look bad.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Using a layout that will not distort the preferred size, show both a JTextField and a JPasswordField side by side.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
JPasswordField should have the same default height as a JTextField.
ACTUAL -
JPasswordField is a few pixels taller than a JTextField.

REPRODUCIBILITY :
This bug can be reproduced always.
