Exception invoking EJB over HTTP is hidden by UT000002 exception

Issue

• We invoke an EJB over HTTP and it throws some exception, but we don't see that main exception. Instead we only see another UT000002 exception thrown trying to handle the original error:

ERROR [org.wildfly.httpclient.common] [] WFHTTP000006: Failed to write exception: java.lang.IllegalStateException: UT000002: The response has already been started

• Can we get the original exception details somehow?
