Thank you, colleagues! Yes, our team is aware of the new SapMachine changes. 🙂 SAP Java Buldpack 2 will start supporting Java 25 with version 2.43.0, which will be released next week (Nov 13). The documentation has been updated (thanks for your suggestions!). You'll see the changes on GitHub and SAP Help Portal with the next SAP BTP release (Nov 13). Best, |
