[jboss-jira] [JBoss JIRA] (AS7-3811) Implement a timeout on EJB client invocations

[Radoslav Husar (JIRA)]

     [ https://issues.jboss.org/browse/AS7-3811?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Radoslav Husar updated AS7-3811:
--------------------------------

    Priority: Major  (was: Critical)


Here is a Jira for the actual problem that invocations are getting stuck: AS7-3975.

Lets keep this Jira for tracking whether the timeout should be implemented or not, needless to say the above Jira needs to be fixed first. If we ensure that client always gets a response, then we might not need a timeout. (But thats probably a whishful thinking.)

> IMHO a client must support a timeout. Very often when things go wrong the clients get stuck indefinitely.
> Maybe this problem go even deeper, something on the server failed but didnt reply to the client. This is often encoutered during failover undeploy test (50 of 200 clients got stuck :-) ).
