> I'm submitting a patch for a crosstalk issue described below.
> I'm trying to debug a problem I'm seeing when running JGroups on the
> same network/machine as another application that is sending/receiving
> data via regular multicast (not through JGroups).  I'm using version
> 2.4.1-SP3.  My scenario is as follows...
> JGroups send on 228.0.0.1:50000
> JGroups receive on 228.0.0.1:50000
> This works fine.  When I start up another application that does
> Sends regular multicast on 228.0.0.2:50000
> Receives regular multicast on 228.0.0.2:50000

> May 15, 2007 4:47:59 PM org.jgroups.protocols.TP handleIncomingPacket
> WARNING: packet from 192.168.101.133:36594 has different version
> (26725) from ours (2.4.1). Packet is discarded
> The patch is in UDP.java:
