Hi Alan, Mandy so far I unfortunately do not have the sources.

Here are as far as I can see the most important jars, with module descriptions.
I wondered about the com.sap.nw.performance.commons  requires - I did not notice and export for this one, looked a bit strange to me (this should have been in performance-commons.jar at least the authors told me so ...
