Exception for jdk.internal.loader.ClassLoaders$AppClassLoader with "ProM with UItopia (workshop)"
I have been following the instructions of
In the third URL, when I attempt to run "ProM with UITopia" I receive an exception as follows:
Exception in thread "main" java.lang.ClassCastException: class jdk.internal.loader.ClassLoaders$AppClassLoader cannot be cast to class java.net.URLClassLoader (jdk.internal.loader.ClassLoaders$AppClassLoader and java.net.URLClassLoader are in module java.base of loader 'bootstrap')
I am running Java version 12.0.2, and a web search suggests that the exception would occur with any Java version after 9.xx.
Does anyone have a fix for this issue that will enable the ProM UITopia code to work with Java 12.xx ?
