FULL PRODUCT VERSION :
java version "1.4.0-beta3"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-beta3-b84)
Java HotSpot(TM) Client VM (build 1.4.0-beta3-b84, mixed mode)

Microsoft Windows 2000 [Version 5.00.2195], Solaris 2.8

DESCRIPTION OF THE PROBLEM :

I need to have my own DocumentFilter installed. With JDK1.4 beta everything worked fine, but
under 1.4 beta 3 my DocumentFilter will never be called.

REGRESSION. Last worked in version 1.4.0-beta

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1.Compile and run the code snipped below under JDK 1.4 beta and type something into the JFormattedTextField.
2.Compile and run the code snipped below under JDK 1.4 beta3 and type something into the JFormattedTextField.


EXPECTED VERSUS ACTUAL BEHAVIOR :
Under JDK 1.4 beta you will see the debug line "With JDK 1.4 beta 3 insertString will never be called!"
Running the same with beta3 nothing will happen.

This bug can be reproduced always.
