> Please specify detailed contract of HttpServerAuthenticationMechanismFactory.
> Describe which params are allowed to be null and what happens in that case. Also describe if null return values are allowed from interface methods and when does that could happen.
> You can consider {{javax.security.sasl.SaslServerFactory}} as example of detailed contract.
> For example:
> * Is {{properties}} parameter of {{getMechanismNames()}} allowed to be null?
> * is {{getMechanismNames()}} allowed to return null ?
> * Are any of {{createAuthenticationMechanism()}} parameters allowed to be null?
> ** For {{ServerMechanismFactoryImpl}} implementation {{properties}} could not be null - is it general rule?
>     {code}
>     java.lang.IllegalArgumentException: Parameter 'properties' may not be null
>     at org.wildfly.common.Assert.checkNotNullParamChecked(Assert.java:69)
>     at org.wildfly.common.Assert.checkNotNullParam(Assert.java:47)
>     at org.wildfly.security.http.impl.ServerMechanismFactoryImpl.createAuthenticationMechanism(ServerMechanismFactoryImpl.java:79)
>     {code}
> ** For {{ServerMechanismFactoryImpl}} implementation {{callbackHandler}} could not be null - is it general rule?
>     {code}
>     java.lang.IllegalArgumentException: Parameter 'callbackHandler' may not be null
>     at org.wildfly.common.Assert.checkNotNullParamChecked(Assert.java:69)
>     at org.wildfly.common.Assert.checkNotNullParam(Assert.java:47)
>     at org.wildfly.security.http.impl.ServerMechanismFactoryImpl.createAuthenticationMechanism(ServerMechanismFactoryImpl.java:80)
>     {code}
> ** For {{ServerMechanismFactoryImpl}} implementation {{mechanismName}} could not be null - is it general rule?
>     {code}
>     java.lang.IllegalArgumentException: Parameter 'mechanismName' may not be null
>         at org.wildfly.common.Assert.checkNotNullParamChecked(Assert.java:69)
>         at org.wildfly.common.Assert.checkNotNullParam(Assert.java:47)
>         at org.wildfly.security.http.impl.ServerMechanismFactoryImpl.createAuthenticationMechanism(ServerMechanismFactoryImpl.java:78)
>     {code}
> I would suggest to wrap {{java.lang.IllegalArgumentException}} to HttpAuthenticationException. Otherwise possibility of {{IllegalArgumentException}} should be documented in contract.
> Filing as Critical, as this interface is expected to be implemented by custom factories.
