VMCPStringBuilder needs to use CNI in GCJ, I presume rather than the
overhead of reflection. There already is an implementation in the
gnu.gcj namespace.

Can you be more specific? How is gcj being used as a compiler? Note
that we now use the standard JAVAC= method to specify a specific
compiler, but this was new with 0.97 IIRC.
