Ignition 7.9.10 use an embedded Java 9 JRE for Vision client.
Is there any drawback if we copy this JRE directory on the gateway and use it for the JRE gateway ?
It’s more convenient to have the same Java JRE version for Client/Designer/Gateway, especially if we have created some modules with common CDG scope library.
No, there’s no reason you couldn’t do this. You can certainly also do the same thing with any particular release of Java 8 or 9 to run a 7.9 gateway.
I tried using Java 9 for the gateway and had issues and needed to revert back to Java 8. Errors on Gateway startup… I’d have to try again to capture the error.
Does 7.9 now officially support Java 9 for the GW?
7.9.10 should, not sure about earlier versions.
