Re: [hibernate-dev] object is not an instance of declaring class

Emmanuel, now I'm failing org.hibernate.search.test.proxy.ProxyTest.testDeteleProxy() as it actually succedes but it is annotated as @FailureExpected(jiraKey = "HSEARCH-577") so it seems I've actually fixed the non-resolved HSEARCH-577, is that a correct interpretation of this unit test?
