> Use {{Collection.emptyList()}} for returning an empty list instead of {{return new ArrayList<>
()}}.  The default constructor creates a buffer of size 10 for _ArrayList_ therefore, returning
this static value saves on some memory and GC pressure and saves time not having to allocate
a new internally buffer for each instantiation.
