The "includes" and "isCompatibleWith" methods of MediaType take into account media types with suffices (e.g. application/soap+xml) including wildcards with suffices (e.g. application/*+xml). However before this change, the isWildcardSubtype() method returned true only for subtype "*". Now a media type such as application/*+xml is also recognized as having a wildcard subtype.
