> This is a patch with several small bugfixes for JVMTI unrelated directly to single step
implementation. The following problems are fixed:
> - Field watches callback from JIT should have RAISE_AREA set since it is not an unwindable
code
> - Stack trace on JIT should skip top level VM internal java methods because they are
not supposed to be shown to user
> - Only on interpreter should VM search for breakpoints in the instrumented method bytecode
because on JIT this bytecode is not touched, the compiled code is changed instead
> - When running on interpreter SingleStep event should be sent before Breakpoint event
according to JVMTI spec. ATM there have reverse order
