[jira] [Created] (LUCENE-4141) don't allow Analyzer.offsetGap/posIncGap to be negative

Robert Muir created LUCENE-4141:
-----------------------------------

             Summary: don't allow Analyzer.offsetGap/posIncGap to be negative
                 Key: LUCENE-4141
                 URL: https://issues.apache.org/jira/browse/LUCENE-4141
             Project: Lucene - Java
          Issue Type: Bug
    Affects Versions: 4.0
            Reporter: Robert Muir


unrelated but i thought about this looking at LUCENE-4139: we should check this doesnt make a corrupt index but instead that IW throws a reasonable exception.

here's some initial tests: overflow checks work, but negative values cause things to go backwards undetected.
