(Optional) Update OpenJDK to another version

Beginning in version 12.7.1, Web Help Desk includes the Open Java Development Kit (OpenJDK). This software is a free and open-source implementation of the Oracle Java Platform.

OpenJDK replaces Oracle Java SE 8, which requires a commercial license. By default, Web Help Desk includes a supported OpenJDK version with each release.

If you are running Web Help Desk 12.7.8 or later on a Windows-based server, you can download and install another OpenJDK version, replacing the version included with your release.

Both versions must be identical. For example, if you are running OpenJDK 11.0.15, you can download and install another OpenJDK 11 version. Upgrading from OpenJDK 11 to a later version (such as OpenJDK 13) is not supported.

This procedure is not supported on Linux and macOS deployments.
