Hello,

I've downloaded NiFi 1.9.2. and installed it on my Windows 10 using cmd
window. I currently have Java 12 installed on my computer and executable
from Path.
When I input the following command: "Start run-nifi.bat" I get the usual
gibberish but towards the end 10-15 lines this is what I get: WARNING: An
illegal reflective access operation has occurred

I've been doing some research and have found that for a while Nifi wasn't
compatible with Java 11, however now it is. But I have Java 12 installed,
is Nifi 1.9.2 compatible with Java 12 SDK or is that the issue resulting in
that log output?

Thanks,

Hamza
