+-	Specific consideration regarding migration to Java 11 in Bonita 7.9
+
+	Bonita 7.9 docker image runs with Java 11. If you are migrating from an earlier version which runs Java 7.8 you should validate on a test environment that your custom code is compatible. Aside from just code incompatibility, special attention has to be given to the dependencies of the custom code, as they might either not work in Java 11.
