Summary: [Broker-J][BDB HA] Removal of non existing group member
can end up in broker crash due to uncaught MemberNotFoundException
Key: QPID-8140
URL: https://issues.apache.org/jira/browse/QPID-8140
Project: Qpid
Issue Type: Bug
Components: Broker-J
Affects Versions: qpid-java-broker-7.0.1, qpid-java-broker-7.0.0,
qpid-java-broker-7.0.2
Reporter: Alex Rudyy
When two concurrent requests are made to delete a group member using REST API
for remote replication node, one can successfully remove the node, whilst other
can end-up in unhandled {{MemberNotFoundException}} which crashes the broker.

{code}
For failed requests an exception like the one below is reported
