Since we upgraded from ORM 6.6.7.Final to 6.6.13.Final, we started seeing TCK test failures like:

java.lang.ClassCastException: class com.sun.ts.tests.jpa.core.annotations.temporal.A_Property cannot be cast to class com.sun.ts.tests.jpa.core.annotations.temporal.A_Property (com.sun.ts.tests.jpa.core.annotations.temporal.A_Property is in unnamed module of loader 'deployment.jpa_core_annotations_temporal_vehicles.ear.jpa_core_annotations_temporal_puservlet_vehicle_web.war' @550228f3; com.sun.ts.tests.jpa.core.annotations.temporal.A_Property is in unnamed module of loader 'deployment.jpa_core_annotations_temporal_vehicles.ear' @72389008)
