Oracle has changed its licensing and subscription model for Oracle’s Java. For Java™ 8 or 11+, you will now need to choose one of the following options:

  1. Stay on an unsupported/insecure version of Java™
  2. Pay Oracle a subscription fee for Oracle JDK / Java™
  3. Use a drop-in OpenJDK™ distribution and get free LTS binaries for 5+ years!

The jClarity team co-founded AdoptOpenJDK which is the free ($ and usage) OpenJDK distribution replacement for Oracle’s Java backed by major vendors such as Amazon, Azul, GoDaddy, IBM, Microsoft, Pivotal, Red Hat, SAP, and many others.
