Please update https://github.com/chainguard-dev/cookbook/tree/main/fips/java or create a new one that uses springboot with maven & gradle. To the maven & gradle files please add workaround from https://github.com/bcgit/bc-java/issues/1538 (the bits that must be added to maven and graddle) Such that we have a complete end-to-end working example for springboot.
