> 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:
> {code:java|borderStyle=solid}
> for (int i = 0; i < obj.length; i++) {
>     if (obj[0] == null) {
>         return true;
>     }
> }
> return false;
> {code} 
> 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).
