Derrick <bcc as you're not subscribed> Yes, NiFi 2.0 requires Java 21. I think we can/should make that more clear on the download page and/or in other notes. If you take a look at the readme in the downloaded app you'll see it referencing Java 21 and some other useful info. But we'll improve awareness of that prior to download.
