Problem:

You see:

Caused by: javax.management.MBeanRegistrationException: preRegister() failed: [ObjectName='jboss.remoting:service=NetworkRegistry', Class=org.jboss.remoting.network.NetworkRegistry (org.jboss.remoting.network.NetworkRegistry@76e8a7)]

Solution:

This happens when the etc/hosts file does not contain the correct entries. Edit your etc/hosts file to map the loopback address with the hostname. The etc/hosts file should contain this (in addition to whatever is already present in the file):

127.0.0.1     ip-10-251-110-98 localhost localhost.localdomain localhost4 localhost4.localdomain4

where ip-10-251-110-98 is the hostname (as seen in the exception stack trace, above).
