RFR 8242811: AlgorithmId::getDefaultAlgorithmParameterSpec returns incompatible PSSParameterSpec for an RSASSA-PSS key

Please take a review at

The AlgorithmId::getDefaultAlgorithmParameterSpec method is used internally to retrieve a default AlgorithmParameterSpec to initialize a Signature, mainly be keytool.

The test shows a case where it can be called.
