Requirements for Java Runtime

The LLS requires that JRE be installed on the machine on which the license server runs. Specifically, the server requires the following:

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

Note:The latest Java versions 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.

(Only for releases prior to 2017 R2) 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. See the FlexNet Embedded License Server Release Notes for details.
