SolrJ FacetField should never return null from getValues()
----------------------------------------------------------
Key: SOLR-2027
URL: https://issues.apache.org/jira/browse/SOLR-2027
Project: Solr
Issue Type: Improvement
Components: clients - java
Affects Versions: 1.4.1
Reporter: David Smiley
Priority: Minor
In some circumstances, FacetField.getValues() will return null. I'd like for
my iteration code to simply be:
{code:java}
for (c : ff.getValues() {
// ...
}
{code}
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.
