Termination of the given JBC could be proven:

(0) Obligation:

JBC Problem based on JBC Program:

public class A {
	public void method() {
		while (true);
	}
}


public class ArrayClasses {
	public static void main(String[] args) {
		Random.args = args;
		A[] data = new A[2];
		data[0] = new A();
		data[1] = new B();
		int i = Random.random();
		if (i == 1) data[i].method();
	}
}


public class B extends A {
	public void method() {
		return;
	}
}


public class Random {
  static String[] args;
  static int index = 0;

  public static int random() {
    String string = args[index];
    index++;
    return string.length();
  }
}

(1) JBCToGraph (SOUND transformation)

Constructed TerminationGraph.

(2) Obligation:

Termination Graph based on JBC Program:
ArrayClasses.main([Ljava/lang/String;)V: Graph of 140 nodes with 0 SCCs.

(3) TerminationGraphToSCCProof (SOUND transformation)

Proven termination by absence of SCCs

(4) TRUE
