Swing has repaint problems with JDK-1.2beta4-I with Java Plugin and Netscape4.05 on Solaris 2.6 when using Java plugin 1.1.1 and the SwingSet that comes with the JDK-1.2beta4-I demos. When the app first appears, clicking on any tab throws the exceptions pasted below. Eventually the app stops throwing exceptions and instead allows the user to view the tabbed panes; however, each pane is drawn with parts of other panes left behind.

Steps to reproduce:
0) Point you classpath the /usr/local/java/jdk1.2/solaris
1) Install Netscape 4.05 by going to the Netscape website.
2) Install the latest Java Plugin from their external website.
3) Copy the SwingSet directory to your public_html directory.
4) Modify the SwingSetApplet.html file with the Java Plugin converter so that it requires the plugin.
5) Open that page through your /javaweb/~username connection.
6) Click on the tabs.
RESULT: The following exceptions are thrown. Eventually the app stops throwing exceptions and instead allows the user to view the tabbed panes; however, each pane is drawn with parts of other panes left behind.
