[JBoss JIRA] (WFLY-3421) Rehashing on view change can result in premature session/ejb expiration

by Paul Ferraro (JIRA)

[ https://issues.jboss.org/browse/WFLY-3421?page=com.atlassian.jira.plugin.... ] Paul Ferraro commented on WFLY-3421: ------------------------------------ PR against master was merged.

When a node leaves each node that assumes ownership of the sessions/ejbs that were previously owned by the leaving node schedules expiration of those sessions. However, view change can also lead to ownership changes for any session/ejb. We are currently handling this properly. If a session/ejb changes ownership, the expiration scheduling is never cancelled, and that session/ejb will expire prematurely, unless the node reacquires ownership. When using sticky sessions, this issue is not apparent, since subsequent requests will direct to the previous owner, who will cancel expiration on the old owner and reschedule expiration on the new owner properly. However, this will be a problem for web sessions if sticky sessions is disabled - and for @Stateful EJBs, if the ejb client receives updated affinity information prior to subsequent requests. > There are at least 2 ways to address this: > # When a request arrives for an existing session/ejb, we immediately cancel any scheduled expiration/eviction.

[JBoss JIRA] (DROOLS-479) Pseudo Clock doesn't work for 2 not statements

by Richard Ambridge (JIRA)

[ https://issues.jboss.org/browse/DROOLS-479?page=com.atlassian.jira.plugin... ] Richard Ambridge commented on DROOLS-479: ----------------------------------------- Thanks for the update. I don't understand why the first part of the test works, but not the second? First template is 'if cheese=smelly and no cheese=a after 3 seconds. Then cheese=smelly is inserted, clock advanced 10 seconds.. template fires. Second template is 'if cheese=stinky and no cheese=a after 3 seconds and no cheese=b after 5 seconds. Then cheese=stinky is inserted, clock advanced 10 seconds.. no template. If the first insert is skipped, (e.g comment out lines 109-120) then the second template seems to work fine. The 'fireUntilHalt' is run in the thread, and it should start before any inserts. This does work in 'real time', but the issue is that this is a simplified test case from our development. The real gap in events could be 48 hours, and we can't easily wait that long in junit tests.

[JBoss JIRA] (WFLY-3386) Nullpointer exception on AbstractSessionBeanStore.getLockStore from within Activiti CDI

by Andries Ehlers (JIRA)

[ https://issues.jboss.org/browse/WFLY-3386?page=com.atlassian.jira.plugin.... ] Andries Ehlers commented on WFLY-3386: -------------------------------------- Hi Martin, I did detail it in a previous comment, but just to re-iterate: A web client calls our JAX-RS resource. The JAX-RS resource performs some basic conversion from DTO to internal domain model with Dozer. We have a Stateless Session Bean (injected with @Inject, not @EJB) containing business logic. The Session Bean has an injected Activiti BusinessProcess. There is no JSF involved, no explicit interaction in our code with the conversation scope; its simply Web-Client -> JAX-RS Resource -> Stateless Session Bean -> BusinessProcess. I'm not 100% sure as to the supported CDI version, but based on some JIRA issues I found the are referring to integrating CDI 1.1 etc. Regards, Andries > Nullpointer exception on AbstractSessionBeanStore.getLockStore from within Activiti CDI > --------------------------------------------------------------------------------------- > > Key: WFLY-3386 > URL: https://issues.jboss.org/browse/WFLY-3386 > Project: WildFly > Issue Type: Bug > Security Level: Public(Everyone can see) > Components: CDI / Weld > Affects Versions: 8.0.0.Final > Environment: CentOS, Mac (Mountain Lion). > Reporter: Andries Ehlers > Assignee: Martin Kouba > > Background: > The actual exception seems to be very close the one in issue: WFLY-3001 but we are not using JSF at all, but Activiti CDI. > Not sure if this is a Wildfly or Activiti issue - it could very well be that there is a bug in Activiti with how it manages the CDI scopes. Unfortunately we're at a loss and seeing that the nullpointer is thrown from within a weld AbstractSessionBeanStore, I decided to post it here. Please advise. > Error: > We use Activiti CDI within Wildfly 8.0.0.Final.
