I am indexing HTMl files some of which contain comments
like this: <!--------->.
The initial symptom is a NullPointerException and a new
'_tmpFileToIndex' file in the directory. The cause is
an org.jdom.IllegalDataException caught in
HtmlIndexer.parse and thrown from somewhere in
DomBulder.build. Thus the parse method returns null and
causes the NullPointerException.
Let me know if you need more info...
