[Farah Juma (JIRA)]

     [ https://issues.jboss.org/browse/WFLY-4624?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Farah Juma updated WFLY-4624:
-----------------------------
    Steps to Reproduce: 
Modify standalone-ha.xml as follows:

# Set the JGroups default stack to "tcp"
# Replace the MPING protocol with:
{code:xml}
<protocol type="TCPPING">
    <property name="timeout">30000</property>
    <property name="initial_hosts">127.0.0.1[7600]</property>
    <property name="port_range">0</property>
    <property name="num_initial_members">1</property>
</protocol>
{code}
# Deploy a distributable app
