> Calling {{wrap/unwrap}} methods on {{ExternalSaslServer}} should throw {{IllegalStateException}} as defines [SaslServer contract|http://docs.oracle.com/javase/8/docs/api/javax/security/sasl/SaslServer.html#unwrap-byte:A-int-int-]. Currently it throws a {{SaslException}}.
> We could be inspired by OpenJDK implementation of CRAM-MD5 and do the following in  both methods:
> {code:java}
> if (completed) {
>     throw new IllegalStateException(
>         "EXTERNAL supports neither integrity nor privacy");
> } else {
>     throw new IllegalStateException(
>         "Authentication not completed");
> }
> {code}
