This mostly looks good to me.

One thing that I'm wondering if whether the fixClassname usages could be 
replaced with verifyFixClassname as the former will abort the replace 
when a UTF-8 sequence can't be decoded. I think the comments (which 
pre-date your changes) also need to be re-examined as verifyFixClassname 
as it will return JNI_FALSE when the scan is aborted.
