[jboss-jira] [JBoss JIRA] (ELY-1371) NullPointerException within DigestSaslClient if username is null.

[ https://issues.jboss.org/browse/ELY-1371?page=com.atlassian.jira.plugin.s... ] Darran Lofthouse updated ELY-1371: ---------------------------------- Description: 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).
