Any Container that contains TextField results in java.lang.NullPointerException.
This effects some of the important compontents like FileChooser etc. Because of this bug the client application may not startup. As this is a critical issue so Please fix it as early as possible.

This is reproduable only in Mustang b74 on solaris & linux (RHEL4.0). This may be reproduce because of the 4985353 bug which was fixed in Swing PIT request for 6.0 B74.

Step to Reproduce:-
--------------------
1) Run the attached program ( TestFrame.java)
2) You can see a java.lang.NullPointerException as follows

Because of the TextField FileChooser also effects.
Step to reproduce:
--------------------
1) Run the attached program. (TestFileChooser.java)
2) click on the "Open" button.
3) You can exception as follows.
