In WFLY 13 when you deploy a simple Jar file , WFLY 13 treats the jar as the EJB and starts the "ejb" cache container. ---------------------------------------------------------------------------------------------------------------------- Key: WFLY-10654 URL: https://issues.jboss.org/browse/WFLY-10654 Project: WildFly Issue Type: Bug Components: Clustering, EJB Affects Versions: 13.0.0.Final Reporter: Chao Wang Priority: Major Deployment(from management console) of a simple Jar file in EAP 7.1.x causes the ejb cache container to start , which should not be the case . From EAP 7.1.x onwards @clustered annotation has been depricated and EJB application is required to start clustering , but in contradiction to this even if we deploy ant jar file (let's say ojdbc6.jar ) the container treats it as an EJB application and starts the EJB cache container as seen in the logs below : ~~~~ 1,640 INFO [org.infinispan.remoting.transport.jgroups.JGroupsTransport] (MSC service thread 1-2) ISPN000078: Starting JGroups channel ejb 22:14:21,640 INFO [org.infinispan.remoting.transport.jgroups.JGroupsTransport] (MSC service thread 1-7) ISPN000078: Starting JGroups channel ejb 22:14:21,640 INFO [org.infinispan.remoting.transport.jgroups.JGroupsTransport] (MSC service thread 1-1) ISPN000078: Starting JGroups channel ejb 22:14:21,640 INFO [org.infinispan.remoting.transport.jgroups.JGroupsTransport] (MSC service thread 1-8) ISPN000078: Starting JGroups channel ejb 22:14:21,673 INFO [org.infinispan.remoting.transport.jgroups.JGroupsTransport] (MSC service thread 1-8) ISPN000094: Received new cluster view for channel ejb: [plohia|0] (1) [plohia] 22:14:21,673 INFO [org.infinispan.remoting.transport.jgroups.JGroupsTransport] (MSC service thread 1-2) ISPN000094: Received new cluster view for channel ejb: [plohia|0] (1) [plohia] 22:14:21,676 INFO [org.infinispan.remoting.transport.jgroups.JGroupsTransport] (MSC service thread 1-2) ISPN000079: Channel ejb local address is plohia, physical addresses are [192.168.122.1:55200] 22:14:21,678 INFO [org.infinispan.remoting.transport.jgroups.JGroupsTransport] (MSC service thread 1-8) ISPN000079: Channel ejb local address is plohia, physical addresses are [192.168.122.1:55200] ~~~~
