[ http://jira.jboss.com/jira/browse/EJBTHREE-572?page=comments#action_12409658 ] Michael O'Brien commented on EJBTHREE-572: ------------------------------------------ Hi, There is a fix for the secondary NPE in this bug within EclipseLink M7 under bug#227630 The JBoss SPI implementation for persistenceUnitInfo.getNewTempClassLoader() is causing a NPE problem when using the JBoss4 UniversalClassLoader3 - returning [null] for UCL3.loadClass(entity). A secondary NPE occurs in EclipseLink when trying to use this [null] missing entity class. The workaround is to handle the original NPE and disable weaving for the session. See https://bugs.eclipse.org/227630 https://bugs.eclipse.org/bugs/attachment.cgi?id=96619&action=diff Thank you for raising this issue. /michael -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
