Hey
@Mark Berning, we do this all the time. On Windows, our procedure has always been:
1. Update Java
2. Change <yourCFDirectory>\bin\jvm.config to point to the new java directory.
3. Restart the CF service
4. Change <yourCFDirectory>\jetty\jetty.lax to point to the new java directory.
5. Restart the CF Add-on service
Just a warning but if you use backslashes in your file path, make sure to escape them (ie
C:\ColdFusion2018\cfusion\jetty\jetty.lax
)
