You're the top geeks on the world I'm very very proud to have you as my
friends, I said this morning to you, I know something you don't know,
but I don't remember what it is, Jesus doesn't want to me to remember
and doesn't want me to say to you right now; I'm the google cracker :) the first 4 bytes, 4 imput class on a java object must match the firewall code;
"This means making the constructor private or default access ("package-private"), or being in a package controlled by the package.access security property. Immutable classes themselves should declare fields final and protect against any mutable inputs and outputs as described in Guideline 6-2. Construction of immutable objects can be made easier by providing builders (cf. Effective Java [6])."

How can I access a private constructor of a class?
One way to bypass the restriction is to use reflections:
import java.lang.reflect.Constructor;
public class Example {
public static void main(final String[] args) throws Exception {
Constructor<Foo> constructor = Foo.class.getDeclaredConstructor(new Class[0]);
constructor.setAccessible(true);
Foo foo = constructor.newInstance(new Object[0]);
System.out.println(foo);
}
}
class Foo {
private Foo() {
// private!
}
@Override
public String toString() {
return "I'm a Foo and I'm alright!";
}
}
