If you want to have JWT working for ALL EE things then it's not 
MicroProfile-JWT anymore, isn't? 
It would be much more. Not bad of course, but still way beyond of what 
MicroProfile-JWT defines.

Anyway, I asked myself how to 'slice' this the right way.
And imo the natural interfaces would be somthing like

* JSON-P on the json side. 
* crypto: Whether to use the JCE built-in crypto or an external lib should be 
pluggable. We just need to add a smallish SPI with a few methods.
* JsonWebToken and a way to get 'the' JWT for a single Request. That might be a 
provider interface or a @RequestScoped CDI bean. 

Oh and I assume it does also include a way to _create_ JsonWebTokens, right?
Could not find this part in the microprofile-jwt discussion/source. Anyone?

But apart from that that's it!

Everything else - including HttpServletRequest Principal, EJB isUserInRole, etc 
is an integration aspect in other parts!
The microprofil-jwt impl is perfectly agnostic to TomEE nor anything else. The 
integration and propagation to all the other EE parts is an integration task 
into TomEE. 

If we cut it that way we have a rather cleanish API which we can easily 
maintain in the future. 
If we start to bake in TomEE features into the mp-jwt core then welcome to 
monolith scariness I'd say.

not injected INTO, but the information itself is provided as @RequestScoped 
bean.
Of course you can inject it into anything actually.

Yes, of course the JWT is request scoped. Taken from a HTTP header in a 
ServletFilter usually.

wdyt?
