Upgraded to Java 21 LTS

Today it was a good time to add Java 21.0.6 to the mix, as I have been noticing a few performance specs for the latest versions of the JDK and my Clojure work, so why not? It's as simple as:

  $ brew install --cask temurin@21

and then to make use of it, I just need to use my trusty shell function:

  $ setjdk 21
  $ java -version
  openjdk version "21.0.6" 2025-01-21 LTS
  OpenJDK Runtime Environment Temurin-21.0.6+7 (build 21.0.6+7-LTS)
  OpenJDK 64-Bit Server VM Temurin-21.0.6+7 (build 21.0.6+7-LTS, mixed mode, sharing)

At this point, I can run the REPL and my Clojure app in JDK 21.0.6, and get all the little updates and bug fixes in the latest LTE JDK. 🙂
