Frequently Asked Questions for Java Licensing
Since we recommend using Java with Mirth® Connect, it's important to consider licensing aspects. This topic covers frequently asked questions to help you understand Java licensing for Mirth® Connect.
In 2019, Oracle significantly changed licensing for official Oracle Java releases. You must now purchase a license in order to receive updates to the commercial version of Oracle Java. In response to this change, we officially added support for OpenJDK in Mirth® Connect and the Mirth® Appliance. OpenJDK receives free updates from Oracle for a period of 6 months following each release. While the Oracle OpenJDK distribution is recommended for use with Mirth® Connect, we strive to support third-party OpenJDK distributions as well such as AdoptOpenJDK, Azul Zulu, and Amazon Corretto. Third party distributions may receive extended security and stability updates from their respective communities (longer than Oracle's 6 months), but these are not guaranteed. This section provides a list of common questions and answers you may need when working with Java Licensing while using Mirth® Connect.
