[infinispan-issues] [JBoss JIRA] (ISPN-1885) RPCs can arrive before CommandAwareRpcDispatcher sets its request/response marshaller

    [ https://issues.jboss.org/browse/ISPN-1885?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12670929#comment-12670929 ] 

Galder Zamarreño commented on ISPN-1885:
----------------------------------------

Paul, I don't see how that's causing issues. We construct CommandAwareRpcDispatcher in JGroupsTransport which has a higher start priority than ExternalizerTable and so the latter should be started before the transport. Now, even if you guys started Infinispan's JGroupsTransport in advance, the exception is coming from CacheViewsManagerImpl$ViewTriggerThread.run(), so CacheViewsManagerImpl.start() has executed and that has a start priority of 11, so ExternalizerTable must have been started.

> CommandAwareRpcDispatcher is started before the request/response marshallers are set, which can cause a NotSerializableException if it attempts to handle an RPC during this short period of time.
