But it does stop you recompiling the class without implementing the method - which is a source incompatibility. That's why it is better to add a new method using a mixin interface and test whether the class implements it before invoking it. There's no section on source compatibility in the jls. :-) -- xxxxxxxxxxxxxxxxxxxxxxxxxxxx Adrian Brock Chief Scientist JBoss by Red Hat xxxxxxxxxxxxxxxxxxxxxxxxxxxx
