The javadoc for Package class and Package.isCompatibleWith method says:
 * Specification version numbers use a "Dewey Decimal"
 * syntax that consists of positive decimal integers
 * separated by periods ".", for example, "2.0" or "1.2.3.4.5.6.7".
 * This allows an extensible number to be used to
 * represent major, minor, micro, etc versions.
 * The version number must begin with a number. <p>

 <skip>

 * @exception NumberFormatException if the desired or current version
 * is not of the correct dotted form.

However, the method doesn't throw a NumberFormatException if the dotted form is incorrect.

-----Here is a test------------
public class PackageTest {

    public static void main(String args[]) {
        Package p = Object.class.getPackage();
        System.out.println(p.isCompatibleWith(""));
        System.out.println(p.isCompatibleWith("0...."));
        System.out.println(p.isCompatibleWith("2.-2"));
        System.out.println("Failed");
    }

}
------Sample run (JDK 1.2.2)-------------
% java PackageTest
true
true
false
Failed
