Careful with that axe^H^H^H static, Eugene!

557403262_2d8d8a3576_b An other instance from the “bugs which will bite you” series:

public class TestStatic {
    static class Foo {
        static Foo instance = new Foo();
        static String name = Foo.class.getName();

        public Foo() {
            System.err.println("Hello, my name is " + name);
        }
    }

    public static void main(String[] args) {
        System.err.println("Your name is what?\n"
            + "Your name is who?\n");

        new Foo();
    }

}

Can you spot the bug? Hint, here is the output:

Your name is what? Your name is who?

Hello, my name is null
Hello, my name is TestStatic$Foo

A final hint: here is what FindBugs reports on the third line: SI_INSTANCE_BEFORE_FINALS_ASSIGNED

Yet an other reason to reduce your FindBugs count to zero before releasing software!
