Description
In some circumstances, FacetField.getValues() will return null. I'd like for my iteration code to simply be:
for (c : ff.getValues() { // ... }
However this will throw an NPE if I don't wrap this in either a null check or this check: ff.getValueCount() > 0
I propose that getValues() return a Collections.EMPTY_LIST if the internal value is null.
