--------------------------------
Summary: (0-10) Absence of destination to message.subscribe flag
causes Java Broker to NPE
Key: QPID-6234
URL: https://issues.apache.org/jira/browse/QPID-6234
Project: Qpid
Issue Type: Bug
Components: Java Broker
Affects Versions: 0.31
Reporter: Keith Wall
If I pass a message.subscribe command to the Java Broker but omit the optional
destination flag, the test fails and the Java Broker exits due to the following
NPE.
It appears the code assumes destination will never be absent.
The easiest way to reproduce the issue is to run Python test (which is excluded
in the Java010PythonExcludes file)
qpid_tests.broker_0_10.queue.QueueTests.test_declare_exclusive_alreadyinuse
Exception is:
