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
implementation.

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 to contribute this patch.

The java.lang.instrument API is maintained by serviceability-dev so that would be the best place to bring that specific issue.
