-----------------------------------------------------------------------------
Key: LUCENE-3049
URL: https://issues.apache.org/jira/browse/LUCENE-3049
Project: Lucene - Java
Issue Type: Bug
Components: contrib/analyzers
Affects Versions: 3.1
Reporter: Jonathan Young
Calling HHMMSegmenter.process() on a string which is longer than 32767
characters will usually result in a NullPointerException being thrown with the
following backtrace:
java.lang.NullPointerException
at
org.apache.lucene.analysis.cn.smart.hhmm.BiSegGraph.getShortPath(BiSegGraph.java:190)
at
org.apache.lucene.analysis.cn.smart.hhmm.HHMMSegmenter.process(HHMMSegmenter.java:208)
The root cause is the declaration of index as a _short_ at line 77 of
modules/analysis/smartcn/src/java/org/apache/lucene/analysis/cn/smart/hhmm/SegGraph.java
.
