Suggested fix in ParseUtil:

Replace 

            if (maxParseTime!=-1)
                       parseResult = runParser(parsers[i], content);
            else 
                       parseResult = parsers[i].getParse(content);

with

      try
      {
            if (maxParseTime!=-1)
                       parseResult = runParser(parsers[i], content);
            else 
                       parseResult = parsers[i].getParse(content);
      } catch( Throwable e )
      {
        LOG.warn( "Parsing " + content.getUrl() + " with " + 
parsers[i].getClass().getName() + " failed: " + e.getMessage() ) ;
        parseResult = null ;
      }
