Java Prerequisites

The following are the Java prerequisites for the machine on which the FlexNet Embedded local license server is installed:

Oracle Java SE 8, OpenJDK 8, or OpenJDK 11.

Note:The latest Java versions that are supported by the license server (Java 8 or 11) are needed for AWS certificate support. If an older Java version is used, the FlexNet Embedded license server cannot communicate with FlexNet Operations on AWS.

A 64-bit JRE for a 64-bit license server or a 32-bit JRE for a 32-bit license server (not adhering to this requirement can cause the license server to fail to start)
Windows only: The JAVA_HOME (or JRE_HOME) environment variable on your system set to the path for your default JDK (or JRE) installation.

Note:The license server requires only the JRE component. If JRE is your default Java installation, set the JRE_HOME environment variable; if JDK is your default installation, set JAVA_HOME.

Early Notification: Local License Server Migration to Higher Java Version

Note:This migration was originally announced for 2023. It is now planned for 2024.

In a future release in 2024, the FlexNet Embedded local license server will migrate to a higher Java version (Java 11 or 17), with no backward compatibility. As a consequence, the updated local license server will no longer run on Java 8.

Older releases of the FlexNet Embedded local license server (released before the license server migration to the higher Java version) will continue to work on Java 8 and are supported as per the FlexNet Embedded Lifecycle Timeline.
