Purpose: Consider upgrading to Java 6 requirement.

Just a couple of people started Autoplot with Java 5, according to the web logs. The impact would be small.

• KeyChain.java has writeKeysFile, which is a text file dumping all the known keys. With Java 6 this could be made to be readable only by the file's owner.
• IOExceptions that have initial cause. Right now there is a bunch of code where the cause's message is preserved, but not the source exception.
• Errors java 5 shows with @override annotation with inner classes. "./org/autoplot/pngwalk/GridPngWalkView.java:87: method does not override a method from its superclass" but it does...
• java 5 shows lots of bugs with the GUIs. It works, but menus are drawn in the wrong place and much of the GUI takes a while to initially paint on Linux.

• The Autoplot used by the Plasma Wave Group is already built with Java 6.
