[wildfly-dev] Read Elytron security domain from Undertow's ApplicationSecurityDomainService

Hello Jim,

Sorry I haven't had a chance to try your reproducer but I am currently
debugging another issue and I think the solution for this issue may
actually help with the problem you are having.

https://issues.redhat.com/browse/WFLY-13319

In the case I am looking into the EJB deployment unit processors are being
executed before it has been determined, I have been considering whether I
could tweak the order of one of the DUPs but that is not possible due to
the dependencies so I need another solution anyway.

What I am presently thinking is during the Phase.STRUCTURE I could add an
empty "SecurityMetaData" object as an attachment to the DeploymentUnit,
initially this will just contain a single value which will be the
ServiceName of the Elytron SecurityDomain to use and will default to "null".

The first DeploymentUnitProcessor to identify that an Elytron
SecurityDomain is to be used will then set the ServiceName of the
SecurityDomain to use.

Longer term we will be removing the application-security-domain resources
as they were just to enable coexistence with legacy security so at some
point in the future deployments will either be secured using Elytron or
will be unsecured and having a common SecurityMetaData can act as the
shared base for the future.

Can you please confirm from which of the Web Services
DeploymentUnitProcessors you need access to this, we will probably need to
double check if any other checks need pulling further forward, so far we
have one happens in Phase.PARSE, one in Phase.POST, and one in
Phase.INSTALL.  Ideally long term we will pull all of this identification
back to Phase.PARSE.

Regards,
Darran Lofthouse.
