I've installed NiFi 1.14.0 on a Windows Server 2019 machine with OpenJDK 16.0.2.
No changes to properties or anything, just unzipped these and set the PATH and
JAVA_HOME environment variables.
I execute the run-nifi.bat file and it runs for a minute and exits.
The nifi-bootstrap.log file contains this:

Maybe this is an OpenJDK issue?
TBH, I haven't spent nearly enough time reading the docs at this point but I
thought it might just run out of the box. So, it could be operator error on my
part too.
Thoughts?
Thanks,
