A DESCRIPTION OF THE PROBLEM :
I am the author of a small OpenSource flashcard application (http://pauker.sourceforge.net/). It works great with Java 1.4.x. Users reported that it does not work with Java 1.5 Beta. So I took a closer look at your latest release candidate of Java 5 and I found a problem with the focus handling of JTextAreas (in combination with JComboBoxes).

Short description:
I have one JComboBox with font names and two JTextAreas with potentially different fonts. If the user selects a font from the JComboBox the font of the focussed JTextArea changes. If the user clicks into one JTextArea the JComboBox displays the active font of the selected JTextArea.

If the program is run with Java 1.5.0 it is at first impossible to type in any character into the focussed JTextArea. If you type something on the keyboard nothing shows up. All the characters suddenly appear at the other JTextArea if you click on it.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Execute the test case with Java 1.4.2 and see how it should work. Execute the test case with Java 1.5.0 and see how it should NOT work.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
I expect the characters to appear in the focussed JTextArea.
ACTUAL -
The characters appear at another JTextArea if gets the focus.

REPRODUCIBILITY :
This bug can be reproduced always.
