A signature generated by JAVA 8.0_231 (and above) doesn't match that generated by 8.0_221

As I understand it from JAVA 8.0_231 upgraded the Apache Santuario libraries to v2.1.3. From that point a signature using <ds:SignatureMethod Algorithm="http://www.w3.org/2001/04/xmldsig-more#rsa-sha512"/> generates an invalid signature.

I have attached signed files generated using JAVA 8.0_221 and one using JAVA 8.0_301 - all versions from 231 upwards generate invalid signature.

The signature is a requirement of the ROI Revenue services. We have a JAR file set up to generate the signature.

Hopefully this may be fixed by adding additional instructions to the JAR file. I can supply the JAR file and the unsigned XML if required used to generate the signed XML.

I don't know if this is considered a JAVA issue or an Apache issue
