[ https://issues.jboss.org/browse/JBTM-2256?page=com.atlassian.jira.plugin.... ] Gytis Trikleris commented on JBTM-2256: --------------------------------------- Me and Tom went through the stack trace and the code and this was the only cause we could find. However, I can confirm that not adding ExtendedXAResourceRecordMap to the record types map causes expiry scanner to throw java.lang.InstantiationException. It is because AbstractRecord class is used as a default type, if the requested type does not exist. And in such case Class.newInstance() call will always fail, since it is an abstract class. Swapping places of those two lines assures that ExtendedXAResourceRecordMap is added to the record types map before expiry scanner is started. On the other hand, the main reason of this pull request was to check if it doesn't cause our qa tests to fail. I will contact people who raised the bugzilla, to confirm that this issue is fixed, since they can reproduce the error without modifying the code. -- This message was sent by Atlassian JIRA (v6.3.1#6329)
