[drlvm][jit][tc]Race conditions at vm\jitrino\src\main\compilationcontext.cpp: 143
----------------------------------------------------------------------------------

                 Key: HARMONY-4004
                 URL: https://issues.apache.org/jira/browse/HARMONY-4004
             Project: Harmony
          Issue Type: Bug
          Components: DRLVM
            Reporter: Ilya Leviev

TC report on thread unsafe access that result in race condition that occur during concurrent
execution of current() function


if it not affect correctness of execution I will mark it by special API for prevention of
further alarms on this race. 


Write -> Write data-race	
Memory write at "compilationcontext.cpp":143 conflicts with a prior memory write at "compilationcontext.cpp":143
