As Pinaki pointed out, the following line -
if (!jpaEm.isDetached(found)) throw new
IllegalStateException("entity should be detached");
should be -
if (!jpaEm.isDetached(detached)) throw new
IllegalStateException("entity should be detached");
In OpenJPA 1.x, the original entity is not detached. The detach()
method returns a copy of the entity, which is detached. These detach
methods/behaviors are OpenJPA unique and were not in the JPA 1.0 Spec.
In OpenJPA 2.0, the original entity is detached in-place and no copy is
returned, as required by the JPA 2.0 Spec.
