The generated 'WEB-INF/jaxrpc-ri-runtime.xml' packaged and used in the OpenAM war contains double identical entries for 4 of the mappings.
This causes harmless warnings when initialised:
A quick check in past releases indicates that this duplication got introduced from 10.1.0 onwards. (9.5.5 and 10.0.0 are fine).
There is also a second copy of this file in WEB-INF/classes with less definitions. I suspect it is not used but am not 100% sure.
