Interface JDOEntityManagerFactory does not compile with JPA 2.0

The JDO Interface JDOEntityManagerFactory extends both factory interfaces: PersistenceManagerFactory (JDO) and EntityManagerFactory(JPA). Both interfaces define a method getProperties. In JDO PersistenceManagerFactory the method returns Properties and in JPA EntityManagerFactory returns Map<String, Object>.
This retults in an error when compiling the api:
JDOEntityManagerFactory.java:[28,7] types javax.jdo.PersistenceManagerFactory and javax.persistence.EntityManagerFactory are incompatible; both define getProperties(), but with unrelated return types

The the error did not occur earlier, because the api package used geronimo-jpa_3.0_spec as the JPA dependeny, but his is the JPA 1.0 specification. The correct dependency is geronimo-jpa_2.0_spec.

Possible solutions: change JDO PersistenceManagerFactory to return Map<String, Object> or remove the JDOEntityManagerFactory and JDOEntityManger interfaces. Are these being used by anyone?
