A DESCRIPTION OF THE PROBLEM :
The Login Dialog consist of user ID and Password as text fields and JOptionPane is used to add OK and Cancle button. As soon as Dialog launches in windows the focus is at User ID text field, however in solaris the focus is at OK button. Please find the code snippet for the same :
1. LoginDialog.java - constructs user ID and Password text fields

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
With the above java files launch the GUI and observe that focus is at OK button in solaris machine.

Focus should be at user ID text field as in windows(Even for solaris in jre1.4.2 the focus was at user ID text field on in jre1.5 problem is occuring)
ACTUAL -
Focus is not at user ID text field
