outbound connection to remote ejbs attempts to use http upgrade even if protocol="remote" is specified. ------------------------------------------------------------------------------------------------------- Key: WFLY-3431 URL: https://issues.jboss.org/browse/WFLY-3431 Project: WildFly Issue Type: Bug Components: Remoting Affects Versions: 8.0.0.Final Reporter: Jason Essington Assignee: David Lloyd When attempting to connect to remote EJBs running on JBoss AS 7.2.0.Final from WildFly 8.0.0.Final, WildFly chooses to use http upgrade even though the outbound connection specifies protocol="remote" Outbound remoting connections in the wildfly config are defined like: {code:xml} <remote-outbound-connection name="remote-ds-connection" outbound-socket-binding-ref="remote-dataserver" username="calypso_user" security-realm="engine-security-realm" protocol="remote"> <properties> <property name="SASL_POLICY_NOANONYMOUS" value="false"/> <property name="SSL_ENABLED" value="false"/> </properties> </remote-outbound-connection> {code} Yet, when attempting to connect to remote EJBs located on the JBoss AS 7.2.0.Final server, the jboss log shows: {noformat} 11:10:21,581 ERROR [org.jboss.remoting.remote.connection] (Remoting "standalone-dataserver" read-1) JBREM000200: Remote connection failed: java.io.IOException: Received an invalid message length of 1195725856 {noformat} and the stacktrace on wildfly shows: {noformat} 2014-06-02 11:10:21,506 WARN [org.jboss.ejb.client.remoting.ConfigBasedEJBClientContextSelector] (ServerService Thread Pool -- 67) Could not register a EJB receiver for connection to localhost:4447: java.lang.RuntimeException: java.io.EOFException: XNIO000812: Connection closed unexpectedly at org.jboss.ejb.client.remoting.IoFutureHelper.get(IoFutureHelper.java:92) [jboss-ejb-client-2.0.0.Final.jar:2.0.0.Final] ... clipped ...

Yet the errors seem to indicate that WildFly is attempting to use http upgrade.
