Description

Hi,

I'm running lucene-1.2-rc3 with Tomcat 4.0.1 and when performing some phrase
queries a get a NullPointerException. Among the files indexed, I have
one "JavaServer Pages(TM): A Developer's Perspective", an article by Scott
McPherson that can be found in Sun's site (an HTML doc). With a phrase query
like "javaserver pages" Lucene crashes. I was able to reproduce the problem
with a few phrase queries but most of the queries worked fine. I also tried
with lucene-1.2-rc2 and had no problem (using the same index and queries).

Here is a stack trace collected from Tomcat's log file
