At the moment JobScheduler Master and Agent are functionally operational with Java 9 and 10. However the Web Service of an Agent is not.
When calling a Web Service on the Agent an Exception is raised.
In this case a java module is used, which is available in Java 8, but not anymore, starting with Java 9. The package com.sun.management hints to removed implementations.
The JobScheduler Master and the Agent should be fully operational with Java 9 /10.
