With Metal API Validation, the Java 2D macOS Metal pipeline has the
the following error
021-02-13 12:51:01.491 java[14931:12150485] Metal API Validation Enabled
-[MTLDebugBlitCommandEncoder synchronizeTexture:slice:level:]:1198: failed assertion `synchronizeTexture: only applies when resourceOptions(0x20) & MTLResourceStorageModeMask(0xf0) == MTLResourceStorageModeManaged(0x10). NOT MTLResourceStorageModePrivate'

 with many java/awt jtreg ests - other tests may fail because of the same but this is a good sampling
