Current version of Spin is incompatible with Java 16.
I'm aware that Camunda BPM only supports up to Java 14 acording to the Release announcements, but I'm raising it as it may take a while to fix to resolve.
This normally (when using Spin) appeared on startup in all java version from 11 to 15

The vague threat on the last line (that we'd all kinda got used to seeing and ignoring has apparently been realised)
And in Java 16 you now get
