Mikhail Khludnev commented on SOLR-12330:
-----------------------------------------
another NPE on omitting some values in range facets. Here's what seen on
{{distrib=false}}
{quote}
"error": {
"trace": "java.lang.NullPointerException\n\tat
org.apache.solr.search.facet.FacetRangeProcessor.createRangeList(FacetRange.java:216)\n\tat

However, on distributed processing we have:
{quote}
"org.apache.solr.client.solrj.SolrServerException: No live SolrServers
available to handle this request:[http://...
"trace": "org.apache.solr.common.SolrException:
org.apache.solr.client.solrj.SolrServerException: No live SolrServers available

org.apache.solr.handler.component.SearchHandler.handleRequestBody(SearchHandler.java:416)\n\tat

I suppose we can't hunt for those NPE rows one by one, but rater wrap
{{FacetModule}} invocation with {{catch(Exception e) \{throw new
SolrException(...,e);}}}
> Referencing non existing parameter in JSON Facet "filter" either reported too
> little and even might be ignored

> Just encounter such weird behaviour, will recheck and followup.
> {{"filter":["\{!v=$bogus}"]}} responds back with just NPE which makes
> impossible to guess the reason.
> It might be even worse, since {{"filter":[\{"param":"bogus"}]}} seems like
> just silently ignored.
> Once agin, I'll double check.
