javax/swing/JColorChooser/Test4319113.java fails with Metal API validation

Manual test javax/swing/JColorChooser/Test4319113.java with Metal API validation when we select Motif L&F with below assertion :

----------System.err:(3/409)----------
2021-03-02 17:34:13.697 java[33782:311206] Metal API Validation Enabled
2021-03-02 17:34:13.973 system_profiler[33784:311302] Metal API Validation Enabled
-[MTLDebugRenderCommandEncoder validateFramebufferWithRenderPipelineState:]:1257: failed assertion `For stencil attachment, the render pipeline's pixelFormat (MTLPixelFormatInvalid) does not match the framebuffer's pixelFormat (MTLPixelFormatStencil8).'

This looks like regression of JDK-8262496. We need to use "-m" option to run this manual test in jtreg. Test is run in Macbook 13inch early 2015 with 10.15.7.
