During our acceptance testing we found regression, which causes that slave is unable to connect to domain controller, so our customers won't be able to use domain mode in their production environment.

This issue may be related to fix made in BZ960292 (https://github.com/ctomc/wildfly/commit/2848cbe8aeda8290d07dc8cca611bc20afb8b1f5), because I am able to connect slave once I use jboss-as-controller-7.2.0.Final-redhat-6.jar from ER6.

Reproduce on single node:
# go to folder with jboss-eap-6.1.0.ER7.zip
export IP=aaa.bbb.ccc.ddd // use IP address of your machine
unzip -q jboss-eap-6.1.0.ER7.zip
# start domain controller
./jboss-eap-6.1/bin/domain.sh --host-config=host-master.xml -b=$IP -bmanagement=$IP &
# start slave
./jboss-eap-6.1/bin/domain.sh --host-config=host-slave.xml -Djboss.domain.master.address=$IP

This is the output of slave:
