[ http://issues.apache.org/jira/browse/LUCENENET-8?page=comments#action_12441033 ] George Aroush commented on LUCENENET-8: ---------------------------------------
Hi folks, I have submitted this issue as a question to the Java Lucene folks (you can see the email thread about it here: http://mail-archives.apache.org/mod_mbox/lucene-java-dev/200610.mbox/date (scan for FastCharStream.refill as the email subject.) It turned out that this is an issue for Java Lucene as well and it has been fixed for 2.0.1 (see: https://issues.apache.org/jira/browse/LUCENE-388) Given that Java Lucene 2.0.1 is not officially released, and that I am still trying to get Lucene.Net 2.0 out, I will hold off doing any work on this issue. I would add, once 2.0.1 is officially released, this change will be part of Lucene.Net 2.0.1, automatically.
