[drlvm][classloader][tc]Known/proven race conditions markup at vm\vmcore\src\class_support\method_lookup.cpp
at find function
-----------------------------------------------------------------------------------------------------------------------------

                 Key: HARMONY-4045
                 URL: https://issues.apache.org/jira/browse/HARMONY-4045
             Project: Harmony
          Issue Type: Bug
          Components: DRLVM
            Reporter: Ilya Leviev


Known/proven race conditions markup at vm\vmcore\src\class_support\method_lookup.cpp at find
function.

TC report on thread unsafe access that result in race conditions that occur during execution
of find function.

Data-races: 

Memory write at "method_lookup.cpp":241 conflicts with a prior memory read at "method_lookup.cpp":241

	#ifdef VM_STATS
 241        VM_Statistics::get_vm_stats().num_method_lookup_cache_miss++;
	#endif //VM_STATS

As issue related to vm statistic data collection in debug mode and it not affect correctness
of execution I have marked it by special API for prevention of further alarms on this race.
