Unable to deploy a project through rest call on business-central in an Unified Execution Server for BxMS 6.4.x

When using rest call to deploy a project in business-central:

 /business-central/rest/deployment/{deploymentId}/deploy?strategy={strategy}

The asynchronous job executed by org.kie.server.jms.executor.KieExecutorMDB always throws an exception putting the job in ERROR state:

2017-09-11 17:44:34,573 WARN  [org.jbpm.executor.impl.AbstractAvailableJobsExecutor] (Thread-12 (ActiveMQ-client-global-threads-133169988)) Error during command org.kie.remote.services.rest.async.cmd.DeploymentCmd error message org.kie.remote.services.rest.async.cmd.JobType from [Module "deployment.kie-server.war:main" from Service Module Loader]: java.lang.ClassNotFoundException: org.kie.remote.services.rest.async.cmd.JobType from [Module "deployment.kie-server.war:main" from Service Module Loader]
...

The issue happens if org.kie.executor.jms.queue system property is set to queue/KIE.SERVER.EXECUTOR. After requeuing the job from business-central the deployment get executed properly.

It seems that the async job is taken instead by KieExecutorMDB in kie-server.war where there is no library "kie-remote-services-6.5.0.Final-redhat-2.jar". The log line asserts that ClassNotFoundException happens in kie-server.war module class loader.
