boot42-preview

Companion module for the ankurm.com article Spring Boot 4.2 Preview: AMQP 1.0, Buildpack Image Cache and What to Test Now. Everything runs against 4.2.0-M2 (a milestone, not GA) and, where a comparison matters, against 4.1.1 (GA).

Path What it is
pom.xml / pom-41.xml the same project on 4.2.0-M2 and on 4.1.1 (a ${revision} parent does not resolve from a repository, hence two files)
src/test/.../ForwardedHeadersTest what the container believes under each forwarded-header strategy
src/test/.../BindingOrderTest Set and Map iteration order from a properties file
src/broken/UsesRestTemplate.java not built; compiled by the facts script to capture the deprecation warnings
src/main/.../RestClientReplacement the replacement, compiled clean
examples/build-image-cache-fragment.xml not executed (needs Docker and a registry)
output/ every transcript quoted in the article; ./scripts/run-all.sh regenerates them

There is deliberately no docs/ folder: the explanations live in the article.
