It looks like an unnecessary unlock:
// CodeCache is full, disable compilation
// Ought to log this but compile log is only per compile thread
// and we're some non descript Java thread.
MutexUnlocker mu(AdapterHandlerLibrary_lock);
CompileBroker::handle_full_code_cache();
}
We're not actually holding the AdapterHandlerLibrary_lock at this point. I think there's a problem in CompileBroker::handle_full_code_cache as well since it seems to assume it's only called from a compiler thread but create_native_wrapper is executed by whoever calls it.
