The issue for this http://jira.jboss.com/jira/browse/JBCOMMON-43 I've committed the fix and the the testcase to common-core org.jboss.test.util.test.xml.resolver.JBossEntityResolverUnitTestCase. Possible backwards incompatibility in behavior is that schema location registered locally is different from the one in the XML's schemaLocation with the purpose of override. In this case, the schemaLocation from the XML file will be used. And at the moment w/o falling back to the registered one if the one in the XML occured to be invalid.
