[jboss-jira] [JBoss JIRA] (AS7-4872) Linkage error when doing remote JNDI lookup from messaging subsystem

Linkage error when doing remote JNDI lookup from messaging subsystem -------------------------------------------------------------------- Key: AS7-4872 URL: https://issues.jboss.org/browse/AS7-4872 Project: Application Server 7 Issue Type: Bug Components: Naming Affects Versions: 7.1.2.Final (EAP) Reporter: Jeff Mesnil Assignee: jaikiran pai Priority: Minor Working on AS7-4626 to add JMS bridge, the messaging subsystem now need to perform remote JNDI lookup on another AS7 instances. I added the org.jboss.remote-naming to the org.jboss.as.messaging to be able to load org.jboss.naming.remote.client.InitialContextFactory. However this creates a Linkage error: 09:45:42,100 WARN [org.jboss.modules] (MSC service thread 1-4) Failed to define class org.jboss.naming.remote.client.ejb.RemoteNamingEjbClientContextSelector in

does not prevent doing remote lookups but looks ugly when starting the JMS bridge... org.jboss.naming.remote.client.InitialContextFactory is trying to load org.jboss.naming.remote.client.ejb.RemoteNamingEjbClientContextSelector in its static initialization block. This class depends on org.jboss.ejb.client.ContextSelector which is in the org.jboss.ejb-client module. I don't want to add a dependency from org.jboss.as.messaging to org.jboss.ejb-client if I can avoid it. The org.jboss.naming.remote.client.InitialContextFactory defines a SETUP_EJB_CONTEXT property that I could set to false but this property is checked after trying to load the ejb-client class in the static block. afaict, loading the class only after checking the property would be enough to prevent having this error being displayed
