duplicate jdoconfig.xml on classpath during unit tests in Intellij IDEA (9.x pre-release)

Question

As described here, IDEA is adding the jdoconfig.xml to the class path twice during unit test runs. Can anyone suggest a work-around for this?

For the time being you could pass the PersistenceManagerFactory's properties programmatically, so without using a jdoconfig.xml file, e.g.

private static PersistenceManagerFactory pmfInstance;

static {
    Map props = new HashMap();
    props.put("javax.jdo.PersistenceManagerFactoryClass", "org.datanucleus.store.appengine.jdo.DatastoreJDOPersistenceManagerFactory");
    props.put("javax.jdo.option.ConnectionURL", "appengine");
    props.put("javax.jdo.option.NontransactionalRead", "true");
    props.put("javax.jdo.option.NontransactionalWrite", "true");
    props.put("javax.jdo.option.RetainValues", "true");
    props.put("datanucleus.appengine.autoCreateDatastoreTxns", "true");
    pmfInstance = JDOHelper.getPersistenceManagerFactory(props);
}

private PMF() {
}

public static PersistenceManagerFactory get() {
    return pmfInstance;
}
