Description

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(); }

}
