Obligation:
need to prove termination of the following program:
package ClassAnalysisRec;

public class ClassAnalysisRec {
	A field;

	public static void main(String[] args) {
		Random.args = args;
		ClassAnalysisRec t = new ClassAnalysisRec();
		t.field = new A();
		t.field = new B();
		t.eval();
	}

	public void eval() {
		int x = Random.random() % 100;
		this.field.test(x);
	}
}

class A {
	public boolean test(int x) {
		return this.test(x-1);
	}
}

class B extends A {
	public boolean test(int x) {
		if (x <= 0) return true;
		return test(x - 1);
	}
