> If i use LUCENE_VERSION >= 2.9 with smart chinese analyzer, it will crash indexwriter with any reasonable amount of chinese text.
> its especially annoying because it happens in 2.9.1 RC as well.
> this is because the position increments for tokens after stopwords are bogus:
> Here's an example (from test case), where the position increment should be 2, but is instead 91975314!
> {code}
> public void testChineseStopWords2() throws Exception {
> Analyzer ca = new SmartChineseAnalyzer(Version.LUCENE_CURRENT); /* will load stopwords */
> String sentence = "Title:San"; // : is a stopword
> String result[] = { "titl", "san"};
> int startOffsets[] = { 0, 6 };
> int endOffsets[] = { 5, 9 };
> int posIncr[] = { 1, 2 };
> assertAnalyzesTo(ca, sentence, result, startOffsets, endOffsets, posIncr);
> }
> {code}
