Brian Stansberry commented on JBAS-7695:
----------------------------------------
Testing confirms that adding the setInterface call fixes this problem. The exact reason it
fails isn't clear. The problem is the AS doesn't receive the multicast discovery
message, not that the client doesn't receive the UDP unicast response. It's not a
issue of multicast routing between two interfaces in the machine itself; the overall
testsuite does all sorts of multicast communication between two ASs bound to different
interfaces. Further, you can bind the AS to localhost and configure the client to use
jnp.localAddress=<default_address> and it will work fine.

makes it clear that without calling setInterface, the socket will use the default
interface for sending, even if it is bound to lo. It appears there is some problem with
this in the OS X JVMs, i.e. the datagram is not successfully sent. With the missing call
to setInterface added, things work correctly.

Key: JBAS-7695
URL:
https://jira.jboss.org/jira/browse/JBAS-7695
Project: JBoss Application Server
Issue Type: Bug
Security Level: Public(Everyone can see)
Components: jnpserver
Reporter: Brian Stansberry
Assignee: Brian Stansberry
Fix For: 5.1.0.Beta1
Test methods testHaPartitionName and testDiscoveryPort fail on Mac OS in the default
situation where ant property "node0" is localhost. If you configure
-Dnode0=<the_default_address> it passes.
I suspect this is because org.jnp.interfaces.NamingContext.discoverServer() is not
calling MulticastSocket.setInterface() when jnp.localAddress is set. I need to understand
the exact cause of the failure though, as other multicast-based communication (e.g. all
the tests in the tests-clustering target) work fine with node0=localhost.
