[8] Review request for 8032063 Exposing non public API by javax.swing.plaf.metal.MetalFileChooserUI$FilterComboBoxModel

[Alexander Scherbatiy]

Hello,
Could you review the rollback of the fix 8022398:

  bug: https://bugs.openjdk.java.net/browse/JDK-8032063
  webrev: http://cr.openjdk.java.net/~alexsch/8032063/webrev.01

  The fix for the 8022398 exposes an internal class 
sun.swing.AbstractFilterComboBoxModel as a public API.

Thanks,
Alexandr.
