Hi,
I'm seeing a problem mentioned in Solr-42, Highlighting problems with
HTMLStripWhitespaceTokenizerFactory:
https://issues.apache.org/jira/browse/SOLR-42

I'm indexing HTML documents, and am getting reams of "Mark invalid"
IOExceptions:
SEVERE: java.io.IOException: Mark invalid

This is using a ~1 week old version of Solr 1.3 from SVN.

One workaround mentioned in that Jira issue was to move HTML stripping
outside of Solr; can anyone suggest a better approach than that?

Thanks
James
