The incorrect behavior appears in version 18.104.22.168 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:
Instead of "obj", the code should be "obj[i]", as in patch.diff.
If indeed the code is intended to check only "obj", then there is
no need for a loop and the entire method body should be only "return
obj == null;" (I attached patch2.diff, though it's unlikely that
this is the correct behavior).
