We have a section of code that does the text highlight, it was running fine
under lucene 1.9.1, but we are getting the following error after upgrade to
3.6.1. It does not seem to be anything that we have control of. any body
have any suggestion on how to fix this?
Exception while trying to select search results
Caused by:
java.lang.ClassCastException:
org.apache.lucene.search.highlight.TextFragment cannot be cast to
org.apache.lucene.search.highlight.DocumentFragment
org.apache.lucene.search.highlight.FragmentQueue.lessThan(TextHighlighter.java:308)

We call getBestSegments as following:
String[] fragments = highlighter.getBestFragments( analyzer, "Message",
message, mf );
