- Other notes: New Oracle Specific JDK 8 Updates System Property to Fallback to Legacy Base64 Encoding Format
Oracle JDK 8u231 upgraded the Apache Santuario libraries to v2.1.3. This upgrade introduced an issue where XML signature using Base64 encoding resulted in appending
to the encoded output. This behavioral change was made in the Apache Santuario codebase to comply with RFC 2045. The Santuario team has adopted a position of keeping their libraries compliant with RFC 2045.
