[jboss-jira] [JBoss JIRA] (JGRP-2391) BindException on Windows

[Thorsten Marx (Jira)]

    [ https://issues.jboss.org/browse/JGRP-2391?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13804838#comment-13804838 ] 

Thorsten Marx commented on JGRP-2391:
-------------------------------------

Sorry, I did not have any windows image.

It was introduced by a change made for the 4.1.* versions. 

This is more or less the code used in the current version that didn't work on windows:
{code}
InetSocketAddress isa = new InetSocketAddress("239.255.0.113", 1234);
MulticastSocket mcs = new MulticastSocket(isa);
{code}

This is a working version that works on windows.
{code}
InetAddress ia = InetAddress.getByName("239.255.0.113");
MulticastSocket mcs = new MulticastSocket(1234);
mcs.joinGroup(ia);
{code}

I don't know the reason for that change, but maybe this helps a bit.
