Unable to type certain characters into a JPasswordField

Affected J2SE version:
======================
J2SE 6.0 from final to J2SE 6.0 Update 12

Affected Operating Systems:
===========================
Linux (all tested Distributions incl. RedHat and SuSE Linux)
Solaris 8, Solaris 9, Solaris 10

Error Description:
==================
Characters using the "mode shift" modifier can not be typed into
JTextComponents that are not input method enabled.

Typing e.g. "@" (\u0x40, At-sign) or "?" (\u0x20ac, Euro sign) on a
german keyboard where these characters are accessed using Alt-GR-q (@)
and Alt-GR-e into a JPasswordField yields "q" or "e" instead of "@"
and "?".

This behaviour can be reproduced with ordinary JTextFields after calling
enableInputMethods(false) on the JTextField.

This behaviour is a regression from J2SE 5 where the above scenario
worked fine.

Reproduction:
=============
A test case is included in KeyboardTest.jar.

java -jar KeyboardTest.jar

Type into password field on top of the window. In the field below the
type text is mirrored (we use the same document to just display the
text).
In the text are below we output the received key events.

Hi all,

Any updates on this one? The customer is expecting a fix, and I'd appreciate any information that we could share with them.
