Description
Possible null pointer dereference in core/src/java/org/apache/lucene/codecs/blocktree/IntersectTermsEnum.java.
at line 119. The fr.index may be NULL. This result is based on static analysis tools and the details are shown below:
*
106: if (fr.index == null) { 107: fstReader = null; // fr.index is Known NULL here. } else { fstReader = fr.index.getBytesReader(); } // TODO: if the automaton is "smallish" we really // should use the terms index to seek at least to // the initial term and likely to subsequent terms // (or, maybe just fallback to ATE for such cases). // Else the seek cost of loading the frames will be // too costly. 119: final FST.Arc<BytesRef> arc = fr.index.getFirstArc(arcs[0]); // fr.index is dereferenced here and fr.index can be NULL if 107 is arrived.
*
It is not sure if fr.index can be NULL in runtime.
We think it is reasonable to fix it by a test if fr.index is NULL and an error handling.
