jdk.nashorn.internal.runtime.arrays.IntArrayData.convert assertion

Nashorn can show an assertion failure when converting arrays of floats.
This worked in 1.8.0_31, fails in 1.8.0_40, 1.8.0_45.

function floatTest() {
    var jsArray = [35250.123456789];
    var jFloat = Java.to(jsArray, "float[]");
    print(j2jsarray(jFloat));
}

function j2jsarray(jArray) {
    var out = new Array();
    // out[0]=1.2; this will avoid the assertion failure.
    for (var i = 0; i < jArray.length; i++) {
        out[i] = jArray[i];
    }
    return out;
}

floatTest();
