<p style='margin-top:0;margin-bottom:10px;'>When using the PersistenceUnitUtil.getIdentifier method to get the id back from a persisted entity, I have found that it returns null if the entity is a proxy. When accessing the id property of the proxy entity, this has been set correctly. It would appear that the implementation of this method is not correct. Please see the test case described below:</p>
