• upgrade gradle to 7.6.1
• upgrade to kotlin 1.9
• upgrade corda dependencies to 4.12 and java to 17
• update java to 17 for corda workflows
• generate corda 4.12 testnet artifacts
• use bootstrap-states.csv to init corda SimpleStates

chore: updating golang version in docs, and proto-grpc dependencies

Pull Request Requirements

• Rebased onto upstream/main branch and squashed into single commit to help maintainers review it more efficient and to avoid spaghetti git commit graphs that obfuscate which commit did exactly what change, when and, why.
• Have git sign off at the end of commit message to avoid being marked red. You can add -s flag when using git commit command. You may refer to this link for more information.
• Follow the Commit Linting specification. You may refer to this link for more information.

Character Limit

• Pull Request Title and Commit Subject must not exceed 72 characters (including spaces and special characters).
• Commit Message per line must not exceed 80 characters (including spaces and special characters).

@sandeepnRES This is really great, thanks for the long overdue upgrade and testing. I just had several cleanup-related questions and comments.

[VRamakrishna]

@petermetz I think the Corda connector and any examples in the non-Weaver parts of Cacti ought to be similarly upgraded (assuming they have not already been done). This change will allow us to finally escape Java 8 and also avoid periodic vulnerability reports.

@VRamakrishna I couldn't agree more and I was going to propose the exact same thing for the same reasons myself, I'm glad we are thinking alike about this! :-)
I'll send in a pull request soon as well with the cactus corda connector being bumped up to JDK 17, Spring Boot 3 and Gradle 8 and Corda 4.12 as well. I'm very happy about this!

@sandeepnRES Thank you very much, this is great! Please fix the merge conflicts and pass it back for review, but from what I can see right now, we are good to go!

[sandeepnRES]

Hi @petermetz Resolved the conflict. Please review.

[sandeepnRES]

Hi @petermetz there's some docs updates I've also added, those are small changes that Rama and me didn't want to open new PR for, but still is orthogonal to this PR, so that's why I've kept the commit separate.

[petermetz]

@sandeepnRES Sounds good to me. The data-sharing-docker-local CI job has been running for 4 hours - I'm guessing it's stuck. I'll do a rebase onto main and that will trigger the re-run, hopefully it was just a fluke.
