------------------------------------

             Summary: ServiceFactory<Credential> used in API is too strict
                 Key: ELY-1898
                 URL: https://issues.jboss.org/browse/ELY-1898
             Project: WildFly Elytron
          Issue Type: Bug
          Components: API / SPI
    Affects Versions: 1.11.0.CR1
            Reporter: Tristan Tarrant


In several places in the API, `SecurityFactory<Credential>` is used, but its bound is too strict, disallowing passing in specific instances, e.g. `SecurityFactory<GSSKerberosCredential>`.
These should all be replaced with `SecurityFactory<? extends Credential>`.

An example of code that doesn't work:

{code:java}
SecurityFactory<GSSKerberosCredential> ksf = ...;
CredentialSource cs = CredentialSource.fromSecurityFactory(ksf); // Compiler error: required SecurityFactory<Credential> provided SecurityFactory<GSSCredential>
{code}

Similar issue in the following method:

{code:java}
MechanismConfiguration.setServerCredential(SecurityFactory<Credential> credentialFactory)
{code}
