How does this skill handle high-concurrency requirements?

It leverages Java 21 Virtual Threads (Project Loom) and structured concurrency patterns to build lightweight, high-performance concurrent applications.

Does it include database testing patterns?

Absolutely. It promotes the use of TestContainers with JUnit 5 to ensure reliable integration testing for JPA and Hibernate layers.

Can it help with both Maven and Gradle?

Yes, it provides full support for Maven 3.9 and Gradle 8.5+, including Kotlin DSL configurations for build optimization.

Does this skill support older Java versions?

While specifically optimized for Java 21 LTS, it can assist with earlier versions, though it will suggest modernizing to features like records and pattern matching where possible.
