             Summary: [proton-j] make trace logging of transfer frames more 
useful
                 Key: PROTON-957
                 URL: https://issues.apache.org/jira/browse/PROTON-957
             Project: Qpid Proton
          Issue Type: Improvement
          Components: proton-j
    Affects Versions: 0.9.1
            Reporter: Robbie Gemmell
            Assignee: Robbie Gemmell
            Priority: Minor
             Fix For: 0.10


In proton-C, the number of payload bytes in the transfer are always reported, 
then a fixed maximum 1024 char string containing stringified payload is shown, 
and the string is appended with "...(truncated)" whenever it doesnt contain the 
full payload.

In Proton-J, the entire payload is toString'ed and then a much smaller 
semi-fixed (its configurable via system property) maximum 80chars of 
stringified payload is shown, and if this is not the full string then the total 
number of characters in the string is displayed. This gives you no usable idea 
of how many bytes are in the remaining or overall payload since each byte uses 
1 or 4chars to display.

To make things more aligned and more usable, the output should be updated to be 
more like proton-c, logging the total payload size in the transfer first, then 
the stringified content which should be increased in length to match proton-c, 
which will make it more usable since it currently only tends to show part of 
the header/properties sections and gets nowhere near the actual body section 
bytes of the message.
