A DESCRIPTION OF THE PROBLEM :
When a component lost it focus and at focusLost() you show a JOptionPane.showMessage(), calling requestFocus of the same component that lost it causes a second call to focusLost().

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
When focus goes to text2, shows a message, then when finish to show the message, text1 request focus, and then focusEvent is callend again( no idea by what )


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Do not call two times the focusEvent when forcing the focus on the component that fires focusEvent.
ACTUAL -
Calls focusEvent once again after requestFocus() on the same component after displays a modal JDialog

REPRODUCIBILITY :
This bug can be reproduced always.
