# boot42-rc1-checklist

Companion module for the ankurm.com article *Spring Framework 7.1 and Spring Boot 4.2: What's Coming and How to Prepare*.
Everything runs against **Spring Boot 4.2.0-RC1** (Spring Framework 7.1.0-RC1; a release candidate, **not GA**) and, for the before/after comparison, against **4.1.2** (GA). JDK 25.

| Path | What it is |
|---|---|
| `pom.xml` / `pom-41.xml` | the same project on 4.2.0-RC1 and on 4.1.2 (a `${revision}` parent does not resolve from a repository, hence two files) |
| `src/test/.../DefaultValuePlaceholderTest` | `@DefaultValue` with a `${...}` placeholder: resolved on 4.2, literal text on 4.1.2 (and a startup failure for an `int`) |
| `src/test/.../KafkaAdminBindingTest` | the new `spring.kafka.template.admin.*` / `listener.admin.*` keys: 5 of 5 bind on 4.2, 0 of 5 on 4.1.2 with no error |
| `src/test/.../LdapEmbeddedSslTest` | embedded LDAP `ssl.enabled=true` without a bundle: fails on 4.2, starts on 4.1.2 |
| `src/test/.../MigratorTest` | what `spring-boot-properties-migrator` prints for the relocated Tomcat keys and the removed path-matching key |
| `src/broken/UsesRestTemplate.java` | not built; `scripts/compile-broken.sh` compiles it with `-Xlint:deprecation` and keeps the compiler's own message |
| `output/` | every transcript quoted in the article; `./scripts/run-all.sh` regenerates them |

Run: `./scripts/run-all.sh`. Not executed here (they need Docker or a registry): the new default buildpack builder and the image-based build cache.

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