[ http://issues.apache.org/jira/browse/LUCENE-400?page=comments#action_12426327 ] Sebastian Kirsch commented on LUCENE-400: -----------------------------------------
Hi Otis, I did not figure out the problem. Getting rid of Commons Collection should be no problem; I am just using them as FIFOs. However, I do not have the time at the moment to implement this.

(Position increments > 1 in the input stream are usually caused by > removing some tokens, eg. stopwords, from a stream.) > The filter uses CircularFifoBuffer and UnboundedFifoBuffer from Apache > Commons-Collections. > Filter, test case and an analyzer are attached. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
