Can't change JVM in ThingWorx Platform 9.1 from java oracle 8 to OpenJDK

[Gatulz]

Thingworx Platform 9.1 is already supported Open JDK, so I want to change JVM from java oracle 8 to open JDK (I tried with Amazon Corretto 11 and Adopt OpenJDK 11). I have tried to change JAVA_HOME into OpenJDK directory and %JAVA_HOME%\bin to the PATH in System Environment Variable and restart the ThingWorx services, but the JVM used in ThingWorx is still Java oracle 8.

And then, I tried to change JVM version directly from apache tomcat configuration by checklist the "Use Default" check box and restart ThingWorx services, the JVM still not change

And then I tried to set directory of OpenJDK jvm.dll file on the Java Virtual Machine field in apache tomcat configuration, but I got an error when I tried to start ThingWorx service.

Did anyone has successfully change the JVM version on Thingworx 9.1? (especially from java SE 8 to OpenJDK)

Thank you

Hi @tdixit,
Thank you for the reply,
I failed because I skip the step to change JAVA OPTION in tomcat configuration.
I have tried step by step in my local VM and its works, java now changes to OpenJDK.
