I justed started with jBPM, and so following the Getting started from the documentation

Since I didn't had JDK installed, I took the latest version (15) of it.

However trying to login in the Business Central I always got an error. After searching a while, it seems that keycloack is not compatible with the latest versions of JDK. So I had to get the JDK 13 to get it working.

Minor topic but it would be nice that it was mentioned, so a newby don't get stuck immediately.

Thx!
