      use the sub project "server" to build the ear and deploy it
      use runInitialContextClient script or the class
      clients/InitialContext/src SimpleClient
      to invoke the EJB, this EJB will invoke another via @Remote

      You need to add the remote-outbound-configuration like this

      <outbound-connections>
      <remote-outbound-connection name="remote-ejb-connection" outbound-socket-binding-ref="remote-ejb">
      <properties>
      <property name="SASL_POLICY_NOANONYMOUS" value="false"/>
      <property name="SSL_ENABLED" value="false"/>
      </properties>
      </remote-outbound-connection>
      </outbound-connections>
      ....
      <outbound-socket-binding name="remote-ejb">
      <remote-destination host="localhost" port="8180"/>
      </outbound-socket-binding>

      Note the target must not exist.

      As a result the invocation show "call-by-reference"
      If the jboss-ejb-client.xml is removed from the application the invocation show "call-by-value"

      If the server default configuration is used an EJB invocation via @Remote interface is, according to the specification, with call-by-value.

      But if the application is configured with jboss-ejb-client.xml to have a remote-outbound-connection the EJB invocation via @Remote is done as call-by-reference no matter whether the configuration is default or
      <in-vm-remote-interface-invocation pass-by-value="true"/>
      is used when it invokes an inVM EJB.

      This is a violation of the specification and can cause serious unexpected issues at runtime for the application if the parameters or return values are mutable
