Issue222799

A float PyArray will be autoconverted to a double array. Even when the
float array is a valid arg to a java method.

------------------ FILE: test157.py ------------------ 
import test157j

from jarray import *
f = zeros(2,'d');
print test157j.test(f); 
print f

f = zeros(2,'f'); f
print test157j.test(f); 
print f
------------------ END ------------------ 

------------------ FILE: test157j.java ------------------ 
public class test157j {
    public static String test(float[] arr) {
        arr[0]=100; 
        return "float";
    }
    public static String test(double[] arr) {
        arr[0]=100;
        return "double";
    }
}
------------------ END ------------------ 

Fixed in Pyarray where the autoconversion is disabled.
