this is a typical java library bug, and I've both produced and fixed a couple of those myself ;) You get an infinite recursion through calling overridden methods. Class A in library implements public methods b and c, where b internally (and of course undocumentedly ;) calls c. Class B from some user of the library extends A and overrides c to call b. When the user calls the method b of class B it goes straight into an infinite loop. The fix is to avoid calling overridable methods from overridable methods, and to delegate those calls to internal, non-overridable versions of the methods. cheers, dalibor topic __________________________________ Do you Yahoo!?
