I'm a Maven enjoyer, but you do you. I chose Java 23, 'natch, since Java 24 is coming in a week or two. I figured this blog would still be interesting for at least a few weeks. Specifically, I'm using GraalVM, which is an OpenJDK distribution that supports some extra party tricks, including compiling JVM code into operating system- and architecture-specific native code. If you're using a UNIX-compatible OS (Cygwin and Windows Subsystem for Linux on Windows count), then you might try SDKMAN to install and manage your JDK varieties.

The Spring Initializr seized upon the insight that I am using a Servlet engine, added Spring gRPC, Spring Boot's web support, and the bridge that allows you to host gRPC in a Servlet container.
