 Brightspace daemon. The rule checker is called **Personal Prof**, the
 Brightspace integration is called **pp-bs-daemon**. The rule checker is written
-in Rascal, which runs on the Java Virtual Machine. The Brightspace daemon is
-written in Python 3.
+in Rascal, which runs on the Java Virtual Machine (tested with openjdk 11,
+newer probably also works). The Brightspace daemon is written in Python 3.

 For checking assignments you always want pp-bs-daemon.
