--------------------------------
Summary: NPE under the covers when
ConnectionFactory.createConnection("me", null) is called
Key: QPID-4690
URL: https://issues.apache.org/jira/browse/QPID-4690
Project: Qpid
Issue Type: Bug
Components: Java Client
Affects Versions: 0.20
Reporter: Gordon Sim
Assignee: Rajith Attapattu
Priority: Minor
Specifically from line 55 of UsernamePasswordCallbackHandler.java. A null
password should be treated as no password supplied, and should not result in an
obscure NPE:
