      Description

      There is a crash when running J2DDemo, Font2Demo, and SwingSet2Demo test with Metal API Validation.
      I have tested with latest lanai build on MacMini(2018) 10.14.6 with default non-retina display.

      Enabled the following flags
      METAL_DEVICE_WRAPPER_TYPE=1
      MTL_SHADER_VALIDATION=1

      Throws the following error while crashing.
      Application Specific Information:
      -[MTLDebugComputeCommandEncoder _validateThreadsPerThreadgroup:]:951: failed assertion `threadsPerThreadgroup.width(1024) must be <= 256.'

      Following manual jtreg tests are also failing with the same error, we need to use "-m" option for jtreg to run these tests:
