Mouse cursor remains as text cursor even after the mouse cursor is on the menuitem.

Step to reproduce the bug:-
-----------------------------------
1) Run the attached program.
2) Click on "Go" Menu.
3) Click on "Prev' Menu which is under 'Go' Menu.
4) Move the Mouse over 'Message' Menu Item of 'Prev'. Now you can see the upper part of the textfield which is behind the 'Message' MenuItem.
5) Move the Mouse over textfield. The mouse cursor changes to Text cursor.
6) Move the Mouse back over the 'Message' MenuiItem. If you the mouse cursor remains to text cursor then the bug is reproduced.
6) Click on 'Unread Message' MenuItem. This triggers the action & ouput can be seen on the console.

This works fine in Tiger RC b63
bash-3.00$ /net/sqindia/export/disk09/jdk/1.5.0/rc/b63/binaries/solsparc/bin/java -showversion JTextFieldTest
java version "1.5.0-rc"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0-rc-b63)
Java HotSpot(TM) Server VM (build 1.5.0-rc-b63, mixed mode)

And
Mustang b40
bash-3.00$ /net/sqindia/export/disk05/2d-SQE/jdk1.6.0/b40/solaris-sparc/bin/java -showversion JTextFieldTest
java version "1.6.0-ea"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.6.0-ea-b40)
Java HotSpot(TM) Server VM (build 1.6.0-ea-b40, mixed mode)

But fails in Mustang b75
java -showversion JTextFieldTest
java version "1.6.0-beta2"
Java(TM) SE Runtime Environment (build 1.6.0-beta2-b75)
Java HotSpot(TM) Server VM (build 1.6.0-beta2-b75, mixed mode)

As the program pass in tiger rc b63 & mustang b40 , but fails in b75 . hence this is a regression . So this must have been introduced some where after Mustang b40.
