problem running PromLite

 I execute the shell script: ./ then I get the following output (see attachment) but it doesn't start. This is a recent development.

    Problem was solved when  I switched to an earlier java version (8)

    Hello Pieter,

    ProM Lite 1.2 can be used with Java 9 or higher, but then you need to add the option "-Djava.system.class.loader=org.processmining.framework.util.ProMClassLoader" to the Java VM that runs ProM (see the shell script).

    As from Java 9, the default classloader in Java is no longer a URLClassLoader. ProM uses the URLClassLoader to be able to handle loading the ProM packages correctly.

    But we advice to use Java 8, if possible.

    Kind regards,
