Incorrect behavior for ELSupport.containsNulls()

The incorrect behavior appears in version 2.3.14.3 and in revision
1495522. I attached a one-line patch (patch.diff) that fixes it.

Method "ELSupport.containsNulls" checks if the "Object[] obj" array
contains nulls like this:

for (int i = 0; i < obj.length; i++) {
    if (obj[0] == null) {
        return true;
    }
}
return false;

Instead of "obj[0]", the code should be "obj[i]", as in patch.diff.

If indeed the code is intended to check only "obj[0]", then there is
no need for a loop and the entire method body should be only "return
obj[0] == null;" (I attached patch2.diff, though it's unlikely that
this is the correct behavior).
