JDK-8032063 fix was integrated to JDK b126 . The fix actually rolls back the change made to javax.swing.plaf.metal.MetalFileChooserUI.FilterComboBoxModel in b110 .
The corresponding CCC 8032063:
- is not approved;
- specifies that JDK-8032063 should be fixed by another way, namely by moving base class to javax.swing.plaf.basic.BasicFileChooserUI class;
While I understand that FilterComboBoxModel class was simply restored as it was in JDK b109 JDK-8032063 fix changes public API and thus I believe should be CCC approved.
