There is a simple testcase as below. You can see StackOverflowError if run this testcase.
This is a defect of Arrays.sort(double []), I have attached a fix for it.

import java.util.Arrays;

public class SortTest {
    public static void main(String[] args) {
        double[] array = { Double.NaN, 1.0, 2.0, Double.NaN, Double.NaN, 3.0,
                4.0 };
        displayArray(array);
        Arrays.sort(array);
        displayArray(array);

        System.out.println();
    }

    private static void displayArray(double[] array) {
        for (double d : array)
            System.out.print(d + " ");
        System.out.println();
    }
}
