Companion code for "Dockerizing Spring Boot 4: Layered Jars, Buildpacks, Distroless and Image Size Benchmarks". Fat jar on JDK and JRE, layered jar on Debian, Alpine and distroless, jlink, the JDK 25 AOT cache, Paketo buildpacks and Jib, each measured for size on disk and pushed, rebuild delta, startup, user and shell. Also PID 1 and signal handling, the jdeps module gap, AOT cache mismatches and buildpacks memory calculation. Transcripts in docs/output/, regenerated by scripts/run-all.sh.

ca-certificates binding
Used only with -Pcorporate-proxy. Put your proxy's CA certificate here as a .pem file next to
type; the Paketo CA Certificates buildpack adds it to the build container's trust store so the
Java buildpack can download its JRE through a TLS-intercepting proxy.
*.pem files in this directory are git-ignored on purpose - a CA certificate from one network does
not belong in a repository. See docs/04-buildpacks.md.
