> Known/proven race conditions markup at vmcore\src\jit\jit_runtime_support.cpp at rth_type_test_update_stats and rth_update_instanceof_stats functions
> TC report on thread unsafe access that result in race conditions that occur during execution of rth_type_test_update_stats and rth_update_instanceof_stats functions

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