I'm following the instructions to install stardog on macOS:

> **[macOS Installation](https://docs.stardog.com/get-started/install-stardog/macOS-installation)**

I followed the steps for M1. i.e. install rosetta and an x86 JDK.

When I try launching stardog server, I get this error.

stardog-admin server start  
Unrecognized VM option 'UseParallelOldGC'  
Did you mean '(+/-)UseParallelGC'? Error: Could not create the Java Virtual Machine.  
Error: A fatal exception has occurred. Program will exit.

I checked which version of java my terminal is seeing:

java -version  
java version "17.0.1" 2021-10-19 LTS

Whereas the stardog install instructions installs `adoptopenjdk11`

How do I point stardog to the `adoptopenjdk11` version of java?

thanks

Hi,

I believe you would need to set the JAVA\_HOME environment variable to point at the Java 11 jdk.
