I believe this was fixed a while back.
The test cases work for me with 4.1.

Note also that Package.getVersion fails when the class file comes from a
jar.  With the included example you can see this by making a manifest file
(in my example named "J/Man"):

Main-Class: men.gcjpackage.TestPackage

Name: men/gcjpackage/
Specification-Title: JChemPaint
Specification-Version: 2.0
Specification-Vendor: The JChemPaint Project
Implementation-Title: jchempaint
Implementation-Version: 2.0.12
Implementation-Vendor: The JChemPaint Project


Then make a jar:

jar -cv -m J/Man -f J/men.jar men/gcjpackage/*.class

And change the test to:

package men.gcjpackage;

public class TestPackage
{
  public static void main(String[] args)
  {
    System.out.println("ClassLoader: " + TestPackage.class.getClassLoader() );
    Package x = TestPackage.class.getPackage();
    System.out.println("Package: " + x);
    System.out.println("Version: " + x.getImplementationVersion());
  } // main
} // TestPackage


With the JDK the last line prints:

Version: 2.0.12

With gij it prints:

Version: null


As the names suggest, this prevents JChemPaint from working:

Confirmed:
It works when interpreting the byte-code:
earth:~>gij men.gcjpackage.TestPackage
ClassLoader: gnu.gcj.runtime.SystemClassLoader{urls=[file:./], 
parent=gnu.gcj.runtime.ExtensionClassLoader{urls=[], parent=null}}
Package: package men.gcjpackage

But not when natively:
earth:~>!./a
./a.out
ClassLoader: gnu.gcj.runtime.SystemClassLoader{urls=[file:./], 
parent=gnu.gcj.runtime.ExtensionClassLoader{urls=[], parent=null}}
Package: null
