Description

Groovy GDK method dump() produces errors at least since Jave version 16.

Example:

println(new File("foo").dump())

produces

<java.io.File@135957 path=java.lang.IllegalAccessException: class org.codehaus.groovy.runtime.DefaultGroovyMethods
 cannot access a member of class java.io.File (in module java.base) with modifiers "private final"
 status=java.lang.IllegalAccessException: class org.codehaus.groovy.runtime.DefaultGroovyMethods cannot access a
 member of class java.io.File (in module java.base) with modifiers "private transient" prefixLength=java.lang.IllegalAccessException:
 class org.codehaus.groovy.runtime.DefaultGroovyMethods cannot access a member of class java.io.File (in module java.base)
 with modifiers "private final transient" filePath=java.lang.IllegalAccessException: class org.codehaus.groovy.runtime.DefaultGroovyMethods
 cannot access a member of class java.io.File (in module java.base) with modifiers "private transient volatile">

To me the best solution would be to respect Java's access modifiers.
