This patch separates the JNI `FindClass` issue from the review thread

Okay ... so by nulling fromClass in the classloader during
finalization (soon to be moved to the Cleaner) you can now distinguish
between the OnLoad case and the OnUnload case, within FindClass - a
comment to clarify that would be good, please.
Added.
However you still have:
407 if (loader.is_null() &&
but you deleted the initialization of loader:
- 404 loader = Handle(THREAD, k->class_loader());
so it will by default be null. I suppose checking the loader is only a
potential optimization as the name of the class will be uniquely
determined anyway. But the code should be cleaned up.
Good catch. Yes it's an optimization to avoid making the Java call
unnecessary.
