> InputStream is processed after the different version error
> ----------------------------------------------------------

> Key: JGRP-2298
> URL: https://issues.jboss.org/browse/JGRP-2298
> Project: JGroups
> Issue Type: Bug
> Affects Versions: 4.0.11, 4.0.13
> Environment: OS: Debian 8
> Reporter: Boris Kantor
> Assignee: Bela Ban
> Fix For: 4.0.16

> Occasionally JGroups shows up a warning when receiving a message with a different JGroups version:
> {{JGRP000010: packet from 10.10.10.130:7800 has different version (0.0.0) than ours (4.0.11); packet is discarded | (Log4J2LogImpl.java:91)}}
> Although the message is then discarded, the socket connection will be kept open. The input stream still contains data that will be processed and falsly interpreted as the next message.
> If you have bad luck, the next bytes will match the correct version number. This leads then to following errors:
> {code:java}

> When it comes to the payload of the message the size of the payload can be as big as 2GB ({{len=in.readInt();}}). On small machines this will lead to an OutOfMemoryError.
> There is a need for some handling of such misinterpreted messages. Like closing and reopening a socket connection or completely ignoring the following bytes until a new message begins or an other algorithm that would prevent the processing of the remaining bytes.
