Per Alan's request here (
), I am redirecting my initial email to this mailing list ...

I have observed a problem where an unnecessary amount of internal class 
conversion is occurring.

I have a patch which I would like to contribute which represents a 
performance optimisation for this problem in the java.instrument module 

It avoids having to convert all classes from a JVM's internal class format 
to the .class file format, in order to call the ClassFileLoadHook, when no 
java transformer installed.

I would like to pair with a sponsor who could host and review this patch, 
so I can get it contributed.
