[infinispan-issues] [JBoss JIRA] Commented: (ISPN-335) EOFException when fetchPersistentState

[Galder Zamarreno (JIRA)]

    [ https://jira.jboss.org/jira/browse/ISPN-335?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12507317#action_12507317 ] 

Galder Zamarreno commented on ISPN-335:
---------------------------------------

The root cause has been discovered on the reading side: http://pastebin.mozilla.org/698472

2nd consecutive call to startObjectInput() must be called on a different marshaller, otherwise, when start is called a 2nd time on the same marshaller, the stream is closed which is precisely the cause of the EOFException.

I dealt with a similar scenarion in the past making sure the 2nd time a reentrant parameter was passed in so that a diff marshaller was used.

> Unrelated: Also, if I set the preload attribute to true, I expect the store to fetch the persistant state before loading the data from the store but that's not the case.
