Thomas - this looks very good work. A minor comment on the description 
is that you mention that it does not modify any Java APIs but I assume 
there is an opportunity to relax the restrictions specified in 
Instrumentation's redefineClasses and retransformClasses as specify the 
same restrictions as JVMTI today.
