Wow - I did not know at all that GIJ has an integrated jit compiler now.

Its basically a GCJ compiling the code into shared-libs and loading it, 
right?
How fast is the generated code and are the jit-results beeing cached 
from run to run (btw how hard would it to implement this)?

Thanks, lg Clemens
