Jenkins can not start on a TCK compliant JVM that does not have MD5 support

XMLWordPrintable

      Java17(actually JDK14 but 17 is the LTS) removed the mandatory requirement that MD5 needed to be a supported MessageDigest.

      If you attempt to start Jenkins on a JVM that does not have MD5 available it ends in a big mess.

          obviously this is just the outer layer of the onion, once you get past this, there is various other code using MD5 (either directly or indirectly via Util.getDigestOf()
