ClassGraph does not scan java.lang.Object

[sebthom]

I am using this code to get all classes of the java.lang package, however java.lang.Object is missing in the result of scanResult.getClasses();

try (ScanResult scanResult = new ClassGraph() //
   .enableAllInfo() //
   .enableSystemJarsAndModules() //
   .acceptPackages("java.lang") //
   .scan() //
) {
   final var classes = scanResult.getAllClasses();
   for (final ClassInfo classInfo : classes) {
      System.out.println(classInfo.getName());
   }
}

I am using OpenJKD 11 with the latest classgraph release.

@sebthom Thanks for the report -- sorry for the delay.

This is actually intentional, since it was kind of a pain seeing java.lang.Object as the superclass of every toplevel class. I made this (rather arbitrary) decision to suppress Object early on in ClassGraph's history, and I'm a bit worried that if I put it back into the return values of all methods that filter it out, it would break some people's code. Maybe though at least if you specifically enable system jars and modules, this class should be scanned.

This is probably a good candidate for the next major version of ClassGraph (5.0), since that will have breaking changes, but I don't have a timeline for when that will be done.
