Getting following exception at runtime with code above:

java.lang.ClassCastException: class com.sun.proxy.jdk.proxy1.$Proxy0 cannot be cast to class jdk.jpackage.internal.MacApplicationLayout (com.sun.proxy.jdk.proxy1.$Proxy0 is in module jdk.proxy1 of loader 'app'; jdk.jpackage.internal.MacApplicationLayout is in module jdk.jpackage of loader 'app')
