Subject [jira] Commented: (LUCENE-2280) IndexWriter.optimize() throws NullPointerException
Date Thu, 18 Mar 2010 16:34:27 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-2280?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12846984#action_12846984
] 

Michael McCandless commented on LUCENE-2280:
--------------------------------------------

>From the log I can see that you run fine for a long time, opening IW,
indexing a few docs, optimizing, then closing.  Then suddenly the
exceptions start happening on many (but not all) merges, and, merges
involving different segments.  JRE bug seems most likely I guess...

Since you see this only on Windows (not eg on Linux), I think this is
likely not a bug in Lucene but rather something particular about your
Windows env -- virus checker maybe?  Is there anything in the Windows
events log that correlate to when the exceptions start?

Or it could be a JRE bug -- you really should try on different (Sun)
JRE.

I saw an issue logged which is some what related to mine issue (http://mail-archives.apache.org/mod_mbox/lucene-solr-user/200809.mbox/%3C6E4A40DB-5EFC-42DA-A857-D59F4EC3496B@mikemccandless.com%3E)
but the only difference here is I am not using Store.Compress for my fields, i am using Store.NO
instead. please note that I am using IBM JRE for my application.
> Is this an issue with lucene?, if yes it is fixed in which version?
