There is ws deployment failure issue[1] which is caused by Webservice subsystem doesn't correctly get mapped elytron security domain from web deployment's default  "other"
application security domain. I tried to fix this by reading Elytron security domain from Undertow started services, but it looks now ApplicationSecurityDomainService is private static and it doesn't provide a getter which allows to get Elytron security domain. Webservice subsystem requires an Undertow service like ApplicationSecurityDomainService[2] started by EJB subsystem to read the Elytron security domain.  Is it doable to change Undertow's ApplicationSecurityDomainService to provide mapped security domain ? Or any better approach to get the mapped Elytron domain ?
