I have added the smooks explicit lifecycle resource and covered the two memory leaks from earlier. There are still some issues with the codebase, however, but we can address those as part of the 4.7 release.
The issues which stand out at the moment are the removal of the SoapUIClientService and the Smooks usage within the wise integration. I'll create issues for those later this afternoon.
I also noticed that there are a few areas which are creating Smooks instances and not cleaning up, usually because their API does not fit this. The lifecycle code will catch this but it would be better if we can identify these at some point and clean up the associated APIs.
