Java Class.getSimpleName() and .getName() behaving differently on Cacao versus Sun Java

Question

Does any one have any idea why this would be happening?

This is some modified lines from the Java DBus bindings (2.6)

  // don't let people import things which don't have a
  // valid D-Bus interface name
  System.out.println("type.getName: " + type.getName() + "   type.getSimpleName: " + type.getSimpleName() );
  if (type.getName().equals(type.getSimpleName()))  {
      throw new DBusException(_("DBusInterfaces cannot be declared outside a package: " + "type.getName: " + type.getName()
              + "   type.getSimpleName: " + type.getSimpleName() ));
  }      

Now check out the difference in output from Cacao (0.99.4) versus Sun 1.5

@ubuntu:~/tmp/cacao$ java -version
java version "1.5.0_16"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_16-b02)
Java HotSpot(TM) Client VM (build 1.5.0_16-b02, mixed mode, sharing)

@ubuntu:~/tmp/cacao$ cacao -version
java version "1.5.0"
CACAO version 0.99.3+hg

java -Djava.library.path=/usr/lib/classpath:/ho... DBusChat 

type.getName: org.freedesktop.DBus   type.getSimpleName: DBus
...Exception in thread "main" org.freedesktop.dbus.exceptions.DBusExecutionException: Could not get owner of name 'framez.tests.dbus.DbusChatInterface': no such name

versus...

 cacao -Djava.library.path=/usr/lib/classpath:/ho... DBusChat
 type.getName: org.freedesktop.DBus   type.getSimpleName: org.freedesktop.DBus

The Exception is unimportant - its being caused by this behavior... Any ideas? Or is this some weird bug with Cacao.

Does anyone know if .getName() is a VM dependent thing?

Info:

GNU Classpath 0.98 on both JVMs DBus bindings 2.6

Solution

This is most likely a bug in the port of GNU Classpath to the Cacao platform. If I recall correctly, most of the methods in the Classpath version of java.lang.Class delegate to a "vm" class that needs to be implemented for each port of the library.

Certainly Class.getSimpleName() should return the classname without the package qualification.
