Invoking GIJ from SunJDK Swing app?

Sun Sep 17 17:48:00 GMT 2006

I'm writing a processing class that will be used in an existing Swing/SunJDK based application on Mac OSX and Linux. I would like to compile my class to native with gcj and use gij to access it (for speed and AOT optimization purposes). 
My thought is that I could write a c++ library that would be called by the Swing application via JNI. This library could then invoke the gij runtime via CNI and load the natively compiled library. The c++ library would act as a bridge between the two distinct java runtimes. I realize that I would have the overhead of two runtimes, but I still believe the speed payoff could be worth it. 
Does anyone have experience with invoking gij via CNI or could anyone comment on the prudence of my thinking as I map out this possible process?
