[infinispan-issues] [JBoss JIRA] (ISPN-5221) Java Hotrod client, nearcache broken after a org.infinispan.client.hotrod.exceptions.TransportException:: java.net.SocketTimeoutException

[Enrico Olivelli (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-5221?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13046019#comment-13046019 ] 

Enrico Olivelli commented on ISPN-5221:
---------------------------------------

Another consequence of the SocketTimeoutException is that after that error the client only receives "byte[]" beans, as the unmarshaller does not work anymore.

I think that in case of SocketTimeout the inputstream goes out-of-synch and the marshaller cannot do its work properly anymore.

Apart from this last observation, IMHO I think that in case of SocketTimeout the TCP connection should be invalidated and than a new connection, possibily to another server, should be opened, that is to treat the SocketTmeout as a full server failure

> Using the LAZY nearcache (new in 7.1.0Final) when a java.net.SocketTimeoutException occurs against one of the given HotRod server the RemoteCache becames not usable any more
> This happens very frequently in our DEV environment, but I cannot reproduce it inside a test case
> This is the stacktrace
