From the author
Use when writing, reviewing or refactoring modern Java (21+, 25 LTS) — records and sealed interfaces as algebraic data types, exhaustive pattern-matching switch over instanceof ladders, virtual-thread concurrency, structured concurrency and ScopedValue replacing ThreadLocal, Stream and Optional pipelines, compact-constructor validation, parametrized JDBC, and the Maven/Gradle build surface. NOT Spring framework wiring (that is `spring-boot`).

- spring-bootericrisco/rsc-harnessUse when building, reviewing, testing, securing or configuring a Spring Boot 4 / Framework 7 backend — controllers, services, Spring Data JPA, application.yml, SecurityFilterChain, slice tests. NOT plain modern-Java language work like records or virtual threads (that is `java`); NOT engine-level SQL schema/index/EXPLAIN (that is `postgresdb`).Testing★ 255
- java-upgradegithub/awesome-copilotUpgrade a Java project to a newer JDK (11 to 17, 17 to 21, 21 to 25) and adopt the new language and library features. Detects the current Java version from the build files, then loads only the matching per-version guide. Use when the user asks to upgrade Java, modernize Java code, or adopt records, sealed classes, pattern matching, virtual threads or other new Java features. For automated end-to-end upgrades see the modernize-java plugin.Engineering★ 40.4K
- 141-java-refactoring-with-modern-featuresjabrena/plinthUse when you need to refactor Java code to adopt modern Java features (Java 8+) — including migrating anonymous classes to lambdas, replacing Iterator loops with Stream API, adopting Optional for null safety, switching from legacy Date/Calendar to java.time, using collection factory methods, applying text blocks, var inference, or leveraging Java 25 features like flexible constructor bodies and module import declarations. This should trigger for requests such as Review Java code for modern Java development; Apply best practices for modern Java development in Java code; Modernize Java code with records pattern matching or switch expressions; Replace legacy idioms with modern Java features; Adopt Java 8+ language features safely.
