---------------------------------

             Summary: [Java Broker] Json Configuration Store should take deep copy of ConfiguredObjectRecords
                 Key: QPID-5879
                 URL: https://issues.apache.org/jira/browse/QPID-5879
             Project: Qpid
          Issue Type: Improvement
          Components: Java Broker
            Reporter: Rob Godfrey
            Assignee: Rob Godfrey
             Fix For: 0.29


Currently the Json Config Store retains a reference to the ConfiguredObjectRecords passed
in in update and create operations.  If the ConfiguredObjectRecord is actually one generated
from AbstractConfiguredObject.asObjectRecord() then the records value may change, and querying
the attributes of the record will obtain locks on the underlying configured object.

To prevent deadlocks and to ensure that the correct values get written to the store, a deep
copy of the record should be taken before storing.
