You are creating a TermScorer on a composite (non atomic IndexReader like SegmentReader). That's still supported in 3.x, but no longer allowed in 4.0. The backwards layer in 3.x had a bug before Lucene 3.5, so theoretically your code should work on 3.5: https://issues.apache.org/jira/browse/LUCENE-3442
But still: null is a valid return value for scorer()!!! It may return null, if no document can match this query. Means the term does not exist at all.
