Fixup agent so that JVM enables DebugNonSafepoints #133

Closed nitsanw closed 8 years ago

This will fix the need for #132 and always do the right thing :)

I'll take your word for it, but why does CompiledMethodLoad enable DebugNonSafepoints?

nitsanw commented 8 years ago

Because: http://stackoverflow.com/questions/37298962/how-can-jvmti-agent-set-a-jvm-flag-on-startup/37306365#37306365 I tested before/after profiles and it seems to work.
