> Known/proven race conditions markup at vm\vmcore\src\exception\exceptions_jit.cpp at exn_propagate_exception() function
> TC report on thread unsafe access that result in race conditions that occur during execution of exn_propagate_exception (241).
> Write -> Write data-race:
> Memory write at "exceptions_jit.cpp":241 conflicts with a prior memory write at "exceptions_jit.cpp":241
> 239 #ifdef VM_STATS
> 240 exn_class->class_thrown();
> 241 VM_Statistics::get_vm_stats().num_exceptions++;
> #endif // VM_STATS
> 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.
