Misleading error message

Misleading error message from compiler.
<java-code>
public class Foo {
    public static void main(String... args) {
       System.out.println((className.class)obj.getI());
    }
}
</java-code>
<output>
Foo.java:3: ')' expected
       System.out.println((className.class)obj.getI());
                                           ^
1 error
</output>

User can't make any thing from the above error message.
It can be improved for better understaing like illegal cast...
