      Description

      FULL PRODUCT VERSION :
      openjdk version "14-ea" 2020-03-17
      OpenJDK Runtime Environment (build 14-ea+23-1048)
      OpenJDK 64-Bit Server VM (build 14-ea+23-1048, mixed mode, sharing)

      ADDITIONAL OS VERSION INFORMATION :
      RHEL7, Ubuntu 18.04

      A DESCRIPTION OF THE PROBLEM :
      When Look and Feel was switched from GTK to Motif,
      some cells of JTable was displayed with anti-aliasing ON.

      Table Header doesn't have the problem.

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      1. Launch SwingSet2 demo
      2. Switch to JTable demo
      3. Change Look and Feel to Motif
      4. Confirm First Name, Last Name, Favorite Movie are displayed with anti-aliasing OFF.
          This is the expected behavior of Motif LAF. (motif_normal.png)
      5. Change Look and Feel to GTK
      6. Confirm these cells are displayed with anti-aliasing ON.
      7. Change Look and Feel to Motif again

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      Expected:
      These cells, such as First Name, Last Name, and Favorite Movie, are displayed with anti-aliasing OFF. (motif_normal.png)
      Actual:
      These cells were displayed with anti-aliasing ON. (motif_aftergtk.png)

      REPRODUCIBILITY :
      This bug can be reproduced always.

      ADDITIONAL INFORMATION:
      When switching from GTK to Motif Look and Feel, aaHint seems to came from
      javax.swing.laf.synth.SynthTableUI$SynthTableCellRender
      instead of
      javax.swing.table.DefaultTableCellRenderer
