Re: NPE: java.net.UnknownHostException after installing 5.2, same
config as 5.1
Anyone else having this same issue? We have 4 different environments with 4
different broker networks setup, we can't use the same multicast name for
all of them, and we'd prefer not to spell out each server name in the config
file, it's not very flexible. This smells like a bug.

default refers to the 'default' IP address and port, 239.255.2.3:6155.

This new syntax seems odd to me. So what's the point of the name
default now? We should document this in the wiki.

You need to change the format for the uri to specify the group via a
parameter. This is the upshot of the resolution to
http://issues.apache.org/activemq/browse/AMQ-1489 - check out the
detail in the comments.
The required change is of the form:
- <networkConnector uri="multicast://${groupId}"/>
+ <networkConnector uri="multicast://default?group=${groupId}"/>
