Java incompatibilities with GTK theme -- Dapper Flight 5

Hi there,
I'm not even sure if this is worth mentioning, but it does effect ubuntu java users who use the Human gtk theme. Here it goes...

When using a Java application that can use the GTK engine all MenuItems do not appear to highlight properly. You can click a MenuItem dropdown and move your mouse over each item. They should highlight atleast simular to clicking on regular gnome menus (as they do with ClearLooks gtk theme).

There is also atleast one other issue that is explained better below.

Steps to repro:
Install Sun's JDK 5 following the instructions from https://wiki.ubuntu.com/RestrictedFormats. Please ensure to run the update-alternatives afterwards.

Once installed open a terminal and run the following:
 java -jar /usr/lib/j2sdk1.5-sun/demo/plugin/jfc/SwingSet2/SwingSet2.jar

That should open up the SwingSet demo.

Select the second icon on the top row

Click on the Look and Feel menu item and select GTK Look and feel. Notice the high menu highlights as you move through each option.

Once the GTK theme is loaded browse through the menu's... notice that they no longer highlight.

Select the first icon on the menu and examine the console. You should notice some exceptions like the following:

Now I know what your thinking. Sun has a horrible implementation of GTK... I just figured I would point out these incompatibilities. I may try my luck w/ Sun as well.
