Looks sensible for an initial release.

I just had a look at the impl in Soteria, and it's servlet-container-only at this point, and doesn't work on Tomcat because HttpServletRequest isn't injectable. Extending SecurityContext to other containers would presumably require the ability to inject appropriate context objects from those containers as well -- possibly limiting the containers for which SecurityContext could be supported -- or a non-CDI-based integration approach). Having just looked at the RI impl of authenticate, I'm also wondering about the level of dependence on JASPIC, vs. a simple layering on the servlet mechanism.

But I think it still requires significant work, and given how tight the remaining schedule is, I'm concerned about investing that effort in functionality that's redundant to some degree, and could be undertaken, more thoughtfully, in the next security JSR. The HttpAuthenticationMechanism and IdentityStore, by contrast, feel much better defined to me, although there are still some details to work out.

It does provide a uniform syntax across containers, but all three methods (one of which only works in the servlet container) duplicate functions that already exist, albeit with slightly different syntaxes, in every container. The only value we're adding here is syntactical uniformity.
>>>> As currently specified, SecurityContext provides only a subset of the functionality originally envisioned. I confess I'm not as familiar with the earlier plans as I should be, but based on more recent discussions it seems clear that the original vision was for a more complete set of functions. It might make sense to avoid specifying any of the functions until we can consider the API more completely and wholistically and ensure that it presents a concise and cohesive set of functions.
>>>> The EE 8 schedule is very aggressive. SecurityContext isn't extremely complicated, but there is still significant work to finalize the spec and the API, make sure the RI is correct, and, for us here at Oracle, integrate the RI with GlassFish and develop the TCK. I think it's still possible to get all that done for SecurityContext, but in light of the fact that SecurityContext doesn't add any net-new functionality, I think it makes sense to drop SecurityContext so we can focus completely on getting HttpAuthenticationMechanism and IdentityStore done. Those two pieces add a lot of value, and is still significant work to do for them, particularly IdentityStore.
