hg: lanai/lanai: 8230958: AA Geometry rendering is not supported in metal

[Ajit Ghaisas]

Hi Alexey,

  I hope this is still work in progress & not complete yet.
  This change has broken sanity of J2DDemo - with or without anti-aliasing.

  To test - 
1) launch J2DDemo -
/Users/AGHAISAS/jdk_workspace/lanai_ws/one/lanai/build/macosx-x86_64-server-release/images/jdk/bin/java -Dsun.java2d.metal=true  -jar /Users/AGHAISAS/jdk_workspace/lanai_ws/one/lanai/build/macosx-x86_64-server-release/images/jdk/demo/jfc/J2Ddemo/J2Ddemo.jar -antialias=false
2) Click on ‘Lines’ tab - J2DDemo app crashes with this message -

-[MTLIOAccelRenderCommandEncoder bindEmulationArguments]:127: failed assertion `No render pipeline state bound'
Abort trap: 6
 
 Changing antialias=true also results in a crash.

We need to either handle the case where the render pipeline is set OR add a TODO log & set a dummy render pipeline state.

Regards,
Ajit
