java.lang.IllegalStateException: Unable to access CDI is thrown from SOAPHandler in EAP 8.0.3+ and 7.4.19+

Issue

When CDI.current() is called from JAX-WS SOAPHandler, java.lang.IllegalStateException is thrown. It works until JBoss EAP 7.4.18 and 8.0.3.1, but we can see the following WARNING messages in server.log after applying patches 7.4.19+ or 8.0.3+.

EAP 8.0.3.1:
