embedding xpcom browser in osx awt

Has anyone been able to embed the xpcom browser in an awt component on
osx?

I worked on this a bit about 1 month ago.  Here a page I created at the
time:

Sorry it is probably too confusing to be useful.

In the end I was trying to get it to work with a debug version of the
1.8  xpcom.  I found assertions happening because the DeviceContext was
not created on the NS event thread.  The NS event thread I'm referring
to is the one which handles native OSX paint events. 

The DeviceContext is created when XPCOM code is initialized. (I don't
remember the exact method that caused it to be created) I was doing
XPCOM initialization in the java application main method but the main
method is run on a different thread than the NS event thread (in AWT).

I could not see a simple way to execute the XPCOM initialzation code on
the NS event thread.  The best way I came up with was writing a NSView
which was used by a CocoaComponent in Java.  This NSView would be
written to call back to Java in response to messages sent to it from the
CocoaComponent.  This would allow me to run the XPCOM initialization
code on the NS event thread.  I haven't got around to trying this.
