Description

SolrQueryIndex suffers of possible NPE when running exact query calculation method.

 

@Override
public long getSize(SizePrecision precision, long max) {
    long estimate = -1;
    switch (precision) {
        case EXACT:
            // query solr
            SolrQuery countQuery = FilterQueryParser.getQuery(plan.getFilter(), null, this.configuration);
        ...
}

 

The problem is the plan being null causes plan.getSortPlan() in FilterQueryParser throw an NPE.
