[jira] [Created] (QPID-8744) [Broker-J] Jackson ObjectMapper instances shouldn't be created on each method call

Daniil Kirilyuk created QPID-8744:
-------------------------------------

             Summary: [Broker-J] Jackson ObjectMapper instances shouldn't be created on each method call
                 Key: QPID-8744
                 URL: https://issues.apache.org/jira/browse/QPID-8744
             Project: Qpid
          Issue Type: Improvement
          Components: Broker-J
    Affects Versions: qpid-java-broker-10.0.1
            Reporter: Daniil Kirilyuk
             Fix For: qpid-java-broker-10.0.2


Jackson ObjectMapper is thread-safe for both reads and writes once constructed, but relatively expensive to create. The codebase has several locations where new ObjectMapper() is called per method invocation. These should be replaced to private static final fields.
