TCP can cause memory usage when connecting to a non-JGroups service
-------------------------------------------------------------------

                 Key: JGRP-1119
                 URL: https://jira.jboss.org/jira/browse/JGRP-1119
             Project: JGroups
          Issue Type: Bug
    Affects Versions: 2.4.7
            Reporter: Dennis Reed
            Assignee: Bela Ban

JGroups does not verify that it is connecting to a JGroups service before using the data returned.

If it connects to another service (for example if another service is found in TCPPING's scan), it reads the first four bytes, uses it as the size of a buffer, and blocks until it fills the buffer with data (or the server kills the connection).

The symptoms are the same as JGRP-1116.
