In Also in Java Today , Brian McCallister has posted a quick Java puzzle in his blog. We offer it today as something fun to consider while the site is down. Commit to an answer before running the code to see what happens.

A.class is not A.class, when each is loaded by a different class loader. That's only the beginning of the trickiness unveiled by Binildas Christudas in his article Internals of Java Class Loading, in which he shows how multiple class loaders relate to one another, the consequences (and yet necessity) of loading classes from multiple class loaders, and why you might even want to write your own. He says, "all Java programmers should know how the mechanism works and what can be done with it to suit their needs. This can save time that would otherwise have been spent debugging ClassNotFoundException, ClassCastException, etc."

More items in the Mustang wishlist in today's Forums. Keithkml writes "Yes, HTML support sucks, compared to modern browsers, and hasn't improved in a while. I think it would be great if Sun could make a full browser supporting all common standards. Maybe JDIC is where this will happen, but JDIC doesn't allow editing HTML in the browser window."
