It can be part of this bug:
https://glassfish.dev.java.net/issues/show_bug.cgi?id=1234
The mapping descriptors are read using getResourceAsStream (as per the spec
requirement) so if there are more than one file name META-INF/mappings.xml on
your classpath, the provider doesn't know which one to use, and reports a problem.
