[infinispan-issues] [JBoss JIRA] (ISPN-2174) CommandAwareRpcDispatcher swallows thread interruptions

[Manik Surtani (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-2174?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12709140#comment-12709140 ] 

Manik Surtani commented on ISPN-2174:
-------------------------------------

I presume the correct approach should be to check for the interrupted status (expectedResponses == -1) over here - https://github.com/infinispan/infinispan/blob/5.1.x/core/src/main/java/org/infinispan/remoting/transport/jgroups/CommandAwareRpcDispatcher.java#L421 - and if we have at least 1 valid response, proceed as normal with that response (the interrupted flag on the thread should still be set) or if not, log the fact that we were interrupted before receiving all responses.
