[infinispan-issues] [JBoss JIRA] (ISPN-6685) Hot Rod server failed to start due to NPE in PersistenceManagerImpl.preload()

[Gustavo Fernandes (JIRA)]

     [ https://issues.jboss.org/browse/ISPN-6685?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Gustavo Fernandes updated ISPN-6685:
------------------------------------
    Steps to Reproduce: 
* Start a single node server with: 
{{bin/standalone.sh  -c clustered.xml}}

* Start JConsole, and register a .proto file, by calling the {{registerProtoFile}} operation in the {{RemoteQuery}} MBean. The proto file is not important, so the string {{message A {}}} is enough
* Restart the server
