!!binary (tag:yaml.org,2002:binary) fails to parse base64 formatted data as defined by RFC2045 (MIME)

[Former user]

Snakeyaml 1.17 will fail to parse base64 formatted data as defined by RFC2045 (MIME) when explicitly type tagged with !!binary (tag:yaml.org,2002:binary) as defined in http://yaml.org/type/binary.html

From "Example 2.23. Various Explicit Tags" from spec (1.1 and 1.2)

java.lang.IllegalArgumentException: Illegal character in Base64 encoded data.

I note that snakeyaml is managing its own Base64 encoder/decoder. JRE now provides java.util.Base64 but requires java 8, which I don't think is unreasonable as Java 7 has been EOF for over 1.5 years.

I think you may find some answers by reading https://code.google.com/archive/p/snakeyaml/issues/99

Nope, that just says that if I remove the line breaks it works - I knew that, and sure its a work around for this bug, but snakeyaml does not conform to the yaml spec.
