SpringBoot Investigate why the system tests aren't run with Java 25

    strategy:
      matrix:
        java:
          - version: 17
            toolchain: true
          - version: 21
            toolchain: true

See if they run with Java 25, and if not, try to fix that.

Hello! I'm interested in working on this issue. Would it be okay if I take this on?

Hey @hojooo, thanks for the offer. These kinds of infrastructure issues are better solved by us, because we can test them on the CI infrastructure.
