SimpleJavaFileObject.toString() generates URI with some extra message

<testcase>
import java.io.File;
import java.net.URI;
import javax.tools.*;
import static javax.tools.StandardLocation.*;
import static javax.tools.JavaFileObject.Kind.*;

class JFO extends SimpleJavaFileObject {
        public JFO(URI uri, Kind kind) {
            super(uri,kind);
        }
}

public class Foo {
    public static void main(String... arg) throws Exception {
        JavaCompilerTool javac = ToolProvider.getSystemJavaCompilerTool();
        JavaFileManager jfm = javac.getStandardFileManager(null);
        JavaFileObject jfo = jfm.getJavaFileForInput(CLASS_PATH,"Foo",SOURCE);
        System.out.println("From JavaFileManager ->" + jfo.toString());
        SimpleJavaFileObject sjfo = new JFO(jfo.toUri(), SOURCE);
        System.out.println("From SimpleJavaFileObject ->" + sjfo.toString());
    }
}
</testcase>
<output>
From JavaFileManager -> .\Foo.java
From SimpleJavaFileObject -> file:/Y:/MustangTestDev/tools/jsr199/JavaFileObject/JFOTest05/./Foo.java from JFO
</output>

1) In the output of SimpleJavaFileObject.toString() extra message 'from JFO' is not required.
2) There is inconsistency in the toString() message of JavaFileObject of StandardJavaFileManager and SimpleJavaFileObject.toString(). SimpleJavaFileObject generate more of URI.
