I don't think so.

No, I was told that the bytecode backend isn't a "real" backend like
all the others; you also can't compile C++ code using the bytecode
backend as a target.

There is a program floating around the 'net called 'javago' that does
a class->class inlining transformation.  It causes *huge* speedups
for code running in the MSJVM (which does not do runtime inlining),
but doesn't noticably improve HotSpot performance.
