Does JGSS support SPNEGO? If not, and there is a Java ASN.1 parser, it
shouldn't be too hard to add.

I don't know whether JGSS is based on the GSS-API C implementation. The
latter is in turn based on the MIT code with fixed mech glue. SSPI has
a different set of API bindings to GSS-API, however it emits compatible
tokens and thus is wire-equivalent.
