[jboss-jira] [JBoss JIRA] Commented: (JGRP-1119) TCP can cause memory usage when connecting to a non-JGroups service

Bela Ban commented on JGRP-1119:
--------------------------------
Actually, I can't do this !
TCPConnectionMap is *generic*, and a send() doesn't need to ship a version number, so
a read() cannot depend on it ! Reverting this change...
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
Fix For: 2.10
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.
