It is not a bug in JDK 6, but a bug in several parts of the JBoss AS. The problem stems from the improper use of classloaders -- classes should be loaded with Class.forName(name), not obj.class.getClassLoader().loadClass(name). The latter method worked up until JDK 6 due to an unintended side effect of the class loading mechanism. This has already been fixed in JBoss Remoting, but apparently not in other programs.
