EJB remote invocations always execute in IO worker even when not supposed to

When you configure EJB3 subsystem so that remote invocations should be executed in thread pools of EJB3 subsystem instead of IO worker threads:

/subsystem=ejb3/service=remote:write-attribute(name=execute-in-worker,value=false)

This seems to have no effect and invocations are still executed in IO worker threads.

This is a regression, in EAP 7.0 it works correctly.
