      Description

      Since MHs.GWT are heavily shared, -XX:PerBytecodeRecompilationCutoff= and -XX:PerMethodRecompilationCutoff= can be reached. It makes method non-compilable and peak performance falls from the cliff (since the method is never inlined and always interpreted).

      It happens very rarely.
