The UDP port opened for all IPs in the JBoss 7 standalone configuration

The bug is for Jboss 7.1.1.Final (I was not able to select it when I opened the issue)

I launched Jboss 7.1.1.Final on Centos6 using JDK7.

When I check what ports are opened I see the following UDP port opened for all IPs:

netstat -ntulp

Active Internet connections (only servers)

Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name

udp 0 0 :::43676 :::* 2460/java

The port is changing its value each time I restart JBoss.

Where and why the UDP port is configured?

I use `standalone\configuration\standalone.xml` and I can not find any UDP configuration there.

I still can see opened UDP port and I want to close it.
