Tridium transitioned Niagara to the Azul Java Runtime Environment (JRE) beginning with Niagara 4.10u8 and Niagara 4.13u3. These releases and all subsequent Niagara releases utilize Azul JRE and do not require Oracle Java licensing.
NIAGARA SUPERVISOR GUIDANCE
Customers who anticipate deploying NEW Niagara Supervisors running any of the following versions are encouraged to purchase the LEGACY-JRE software option before November 29, 2026 and place those licenses into inventory for future use. The LEGACY-JRE option will not be available for purchase after that date.
These releases require Oracle JRE licensing:
- Niagara 4.9 and earlier
