Conflict between Beryl and AWT/swing [00 original]

My default window manager has always been using Beryl and there is no problem. Whether it is development (Java) or general applications.
When developing Java Desktop applications, I usually use SWT, AWT, and swing for a long time. Today I used them and suddenly found a problem:
When Beryl is enabled for AWT/swing, the control cannot be displayed, that is, it cannot be drawn, and it is depressing.
To Java Development CommunityI read it and said this is a bug in JDK 6 --!
But fortunately, there is a solution: edit/etc/environment:

Sudo gedit/etc/environment

Add this sentence:
Awt_toolkit = "mtoolkit"
Now, the problem can be solved :-)
