Summary

The Swing library has a number of internal classes which at some point in the past were used as a kind of "public" API.

Problem

The list of files which are unused in the Swing, but exists only for compatibility.

The look and feels:
    apple/laf/AquaLookAndFeel.java
    - was replaced by the com.apple.laf.AquaLookAndFeel.java and can be used
          * indirectly via UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
          * or via UIManager.setLookAndFeel("com.apple.laf.AquaLookAndFeel");
    com/sun/java/swing/plaf/nimbus/NimbusLookAndFeel.java
    - was replaced by the javax.swing.plaf.nimbus.NimbusLookAndFeel.java

 Other classes:
    com/sun/java/swing/Painter.java
    com/sun/java/swing/plaf/nimbus/AbstractRegionPainter.java 
    com/apple/eawt/ApplicationAdapter.java
    com/apple/eawt/ApplicationEvent.java
    com/apple/eawt/ApplicationListener.java

Solution

The solution is to remove all these files.

Specification

There are no any changes in the public API specification.
