Ehcache resource conflict

[newbee]

Hello guys,

I am trying to use EhCache Ticket Registry as a storage. I have followed the steps provided in this document. https://apereo.github.io/cas/5.2.x/installation/Ehcache-Ticket-Registry.html

I had to change the name of the xml file to ehcache.xml instead of ehcache-replicated.xml as mentioned in the documentation.

I am getting below error while CAS starts up. Its a warning message. Shall I be concerned?

2018-08-13 11:09:58,706 WARN [net.sf.ehcache.CacheManager] - <Creating a new instance of CacheManager with a CacheManagerPeerListener which has a conflict on a resource that must be unique.
The resource is RMI listener port: 41001.
Attempting automatic resolution. The source of the configuration was DefaultConfigurationSource [ ehcache.xml or ehcache-failsafe.xml ].
To avoid this warning consider using the CacheManager factory methods to create a singleton CacheManager or specifying a separate ehcache configuration (ehcache.xml) for each CacheManager instance.>
2018-08-13 11:09:58,706 WARN [net.sf.ehcache.distribution.RMICacheManagerPeerListener] - <Resolving RMI port conflict by automatically using a free TCP/IP port to listen on: 53897>

Please point anything that I am not doing right here.

My application.properties have these settings.

##
# Ehcache Ticket Registry

cas.ticket.registry.ehcache.configLocation=classpath:/ehcache.xml

The ehcache.xml file looks like below

<ehcache name="ehCacheTicketRegistryCache"
 updateCheck="false"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:noNamespaceSchemaLocation="http://ehcache.org/ehcache.xsd">
