The problem seems to be related to geronimo-jpa_2.0_spec-1.0-PFD2.jar. Removing it from the classpath fixes the problem (so it must be hiding geronimo-jpa_2.0_spec-1.0.jar).
Actually, this is maybe a good opportunity to move to the more recent geronimo-jpa_2.0_spec-1.1.jar (http://repo2.maven.org/maven2/org/apache/geronimo/specs/geronimo-jpa_2.0_spec/1.1/geronimo-jpa_2.0_spec-1.1.jar).
