[jboss-jira] [JBoss JIRA] (ELY-1371) NPE during authentication when using scoped context or legacy remote-naming API

NPE during authentication when using scoped context or legacy remote-naming API ------------------------------------------------------------------------------- Key: ELY-1371 URL: https://issues.jboss.org/browse/ELY-1371 Project: WildFly Elytron Issue Type: Bug Components: SASL Affects Versions: 1.1.2.Final Reporter: Darran Lofthouse Priority: Blocker When running an EJB client which uses scoped context or legacy jboss-remote-naming API to invoke secured EJBs, a NPE occurs. Additionally, in the case with jboss-remote-naming legacy API, after this exception is logged, the client thread freezes (in the scoped context case, the exception propagates to the client thread). This is a regression in 7.1.0.CR2. Reproducer attached. Full stack trace for the case of scoped context: {noformat} Exception in thread "main" org.jboss.ejb.client.RequestSendFailedException: EJBCLIENT000409: No more destinations are available at
