Mark, this is purely related to Digester, not Lucene. It's hard to tell which
method Digester is trying to call, as it uses reflection and the exception
stack trace doesn't show enough. My guess is it always happens on the same XML
element, if you run this multiple times. Add some print calls to see what it
is that Digester chokes on.

Subject: digester/lucene runtime problems
Hi,
We have 500k xml documents in a file. We ran the digest/lucene and get the
following error messages. We had ran a smaller size file with 20k xml
documents without any problems. Can anyone help us to resolve this problem?
Thank you very much.
Regards,
Mark
