Eugene S. Ostrovsky commented on HARMONY-2145:
----------------------------------------------

I've got the point.

But "sum of method's instruction sizes" is a kind of information useless for VM.
VM needs to know what code. addresses are occupied by the method. E.g. all addresses from codetAddr to codetAddr + codeSizze -1. It is ok for VM if further inlined methods' code is also inside this region.

Is it possible for JIT to report codeSize in this sense?

> Current VM doesn't report Compiled Method Load event for methods that are inlined by JIT. 
> Though spec requires it to be sent for every compiled method:
> http://java.sun.com/j2se/1.5.0/docs/guide/jvmti/jvmti.html#CompiledMethodLoad
> We need to add some function to interface between VM and JIT in order to let VM know about inlined methods.
