             Summary: [Java Common] 0-8/9/9-1 parser can cause stack overflow if a frame is broken into many TCP reads/writes
                 Key: QPID-6189
                 URL: https://issues.apache.org/jira/browse/QPID-6189
             Project: Qpid
          Issue Type: Bug
          Components: Java Common
            Reporter: Rob Godfrey
            Assignee: Rob Godfrey
             Fix For: 0.31


When an entire frame is split over many TCP reads/writes the 0-8/9/9-1 codec is effectively using tail recursion to iterate over the buffers to parse the whole frame.  When there are a lot of buffers this can cause stack overflow.  To guard against this we can simply squash the multiple buffers into a single buffer when we cross a threshold number of buffers.
