When I try to start Hazelcast Managment Center, it fails to start - hazelcast

Question

I am trying to Hazelcast 3.2.4 Management Center to start up in TC Server 3.2.4 Tomcat 7. But even though it seems to start without errors in the logs, I can't access the page:
In Tomcat.log I can see
Line 203004: INFO: Deploying web application archive /vc2cmmkb019231n/app/pm13/process-1.3-build317/instances/vm1/webapps/mancenter-3.2.4.war
Line 203016: INFO: notifyApplicationLifecycle(localhost|mancenter-3.2.4)[START]
Line 203018: WARNING: handleStartEvent(localhost|mancenter-3.2.4)[START] failed (ConnectException) to send ping: No current registered listener
Line 204206: INFO: notifyApplicationLifecycle(localhost|mancenter-3.2.4)[STOP]
that indicates that mancenter has started and stopped, but when I try to access the web page:
http://my-host-name:8080/mancenter-3.2.4/
it doesn't load up.
I am using the following hazelcast spring configuration:
<bean id="hcMonitorInstance" class="com.hazelcast.core.Hazelcast" destroy-method="shutdown" factory-method="newHazelcastInstance">
<constructor-arg>
<bean class="com.hazelcast.config.Config">
<property name="instanceName" value="hcMonitorInstanceConfig"/>
<property name="groupConfig">
<bean class="com.hazelcast.config.GroupConfig">
<property name="name" value="${px-monitor-monitor.com.hazelcast.config.GroupConfig.name}"/>
<property name="password" value="${px-monitor-monitor.com.com.hazelcast.config.GroupConfig.password}"/>
</bean>
</property>
<property name="networkConfig">
<bean class="com.hazelcast.config.NetworkConfig">
<property name="join" ref="join"/>
<property name="port" value="${px-monitor-monitor.hazelcastInstanceConfig.port}"/>
<property name="portAutoIncrement" value="true"/> <!--THIS is FALSE in CIWS-->
<property name="interfaces">
<bean class="com.hazelcast.config.InterfacesConfig">
<property name="interfaces">
<list>
<value>*</value>
</list>
</property>
</bean>
</property>
</bean>
</property>
<property name="managementCenterConfig">
<bean class="com.hazelcast.config.ManagementCenterConfig">
<property name="enabled" value="${hz.management.center.enabled}"/>
<property name="url" value="${hz.management.center.url}"/>
</bean>
</property>
</bean>
</constructor-arg>
</bean>
Any Ideas on why it won't start up? I have also looked in Catalina.out for errors, but none show up. I've also tried hitting http://my-host:8080/mancenter/ but that doesn't work either. I can see the web app expanded in tomcat webapps folder and it looks to be correct.

Run java -version. If it is 1.8.0_91 then that's the culprit. Following is what you do
point to an older version of java (1.6 or 1.7 are fine) executable to run the mancenter; something similar to java -jar mancenter-3.6.2.war 8200 mancenter; I ran it on port 8200 so as to not conflict with existing app running on 8080
that should bring up the mancenter; create the admin user
now you should be able to start your 'normal' java version (1.8.0_91 most likely)
It appears the problem occurs with java 1.8.0_91 when no user has been created. Let me know if this worked.
