Hi, all
The case is we need to load an implementation class during VM init and
should terminate it if the class cannot be found.
Here is the code.
inst_class =
(*env)->FindClass(env,
"org/apache/harmony/instrument/internal/InstrumentationImpl");
if(NULL == inst_class){
//VM exits abnormally.
(*env)->FatalError(env,"class cannot find:
org/apache/harmony/instrument/internal/InstrumentationImpl");
}
Thank you.

How far along is this code? Any chance you want to toss up a snapshot
of it so people can look and comment and ... maybe even help?
