    Description

      The javadoc states "Null objects [...] within the iteration are represented by empty strings".

      But when there is exactly one element, Strings::join do not test if it is null.

       Strings.join(Arrays.asList((String)null), '.')

      returns "null" where I expected EMPTY ("")
