Right. The API is lacking a feature that allows you to extend it to
support additional signature algorithms. There is an RFE open for this:
6566047. You can't see it on bugs.sun.com yet, but try in a day or two.
The RFE is to add an API similar to TransformService.

We have added support for RSA_SHA256, RSA_SHA384, RSA_SHA512,
HMAC_SHA256, HMAC_SHA384, and HMAC_SHA512 to OpenJDK. If this is an
important feature to you, we could consider backporting it to JDK 6.

Yes, they will be included in JDK 7.
