It looks like the osgi code has changed for these classes. In the version I was using before, the class looked like this.

So we need to decide which of the two implementations is better (the provided one or the one I wrote). I'd say it would be easier in terms of maintenance to let FrameworkUtil provide new features of the filters rather than us having to keep up. That is unless there is a serious performance issue that needs to be addressed? Currently all filter construction is delegated to FrameworkUtil so if we go with that it would just be a case of deleting my filter implementation. P.S. The same looks to be true for AdminPermission (although I never implemeted that :-) View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4251559#...
