[jira] [Created] (PROTON-1967) Reduce garbage created in the Transport layer

Timothy Bish created PROTON-1967:
------------------------------------

             Summary: Reduce garbage created in the Transport layer
                 Key: PROTON-1967
                 URL: https://issues.apache.org/jira/browse/PROTON-1967
             Project: Qpid Proton
          Issue Type: Improvement
          Components: proton-j
    Affects Versions: proton-j-0.30.0
            Reporter: Timothy Bish
            Assignee: Timothy Bish
             Fix For: proton-j-0.31.0


The Transport implementation currently creates a new Transfer, Flow, and Disposition object for each write to the FrameWriter which creates an excessive amount of unnecessary throw away objects.  The Transport can cache a single instance of each type and properly fill the fields (or set to defaults) on each write to ensure consistency. 

This change requires adding a copy method to the types such that the tests that intercept written frame data objects can create a copy for later analysis.
