Hi,
I've tried installing the latest (3rd) RC for Solr 1.4 and Lucene 2.9.1. One of
our integration tests, which runs against and embedded server appears to be
failing on highlighting. I've included the stack trace and the configuration
from solrconf. I'd appreciate any insights. Please let me know what additional
information would be useful.

I see in our solrconf the following for highlighting.
<highlighting>
<!-- Configure the standard fragmenter -->
<!-- This could most likely be commented out in the "default" case -->
<fragmenter name="gap" class="org.apache.solr.highlight.GapFragmenter"
default="true">
<lst name="defaults">
<int name="hl.fragsize">100</int>
</lst>
</fragmenter>
<!-- A regular-expression-based fragmenter (f.i., for sentence extraction)
-->
<fragmenter name="regex" class="org.apache.solr.highlight.RegexFragmenter">
<lst name="defaults">
<!-- slightly smaller fragsizes work better because of slop -->
<int name="hl.fragsize">70</int>
<!-- allow 50% slop on fragment sizes -->
<float name="hl.regex.slop">0.5</float>
<!-- a basic sentence pattern -->
<str name="hl.regex.pattern">[-\w ,/\n\"']{20,200}</str>
</lst>
</fragmenter>
<!-- Configure the standard formatter -->
<formatter name="html" class="org.apache.solr.highlight.HtmlFormatter"
default="true">
<lst name="defaults">
<str name="hl.simple.pre"><![CDATA[<strong>]]></str>
<str name="hl.simple.post"><![CDATA[</strong>]]></str>
</lst>
</formatter>
</highlighting>
Thanks,
