Date Tue, 23 Feb 2010 07:05:28 GMT
IndexWriter.optimize() throws NullPointerException
--------------------------------------------------

                 Key: LUCENE-2280
                 URL: https://issues.apache.org/jira/browse/LUCENE-2280
             Project: Lucene - Java
          Issue Type: Bug
          Components: Index
    Affects Versions: 2.3.2
         Environment: Win 2003, lucene version 2.3.2, IBM JRE 1.6
            Reporter: Ritesh Nigam


I am using lucene 2.3.2 search APIs for my application, i am indexing 45GB database which
creates approax 200MB index file, after finishing the indexing and while running optimize()
i can see NullPointerExcception thrown in my log and index file is getting corrupted, log
says

------------------------------------------------------------------------
Caused by: 
java.lang.NullPointerException
	at org.apache.lucene.store.BufferedIndexOutput.writeBytes(BufferedIndexOutput.java:49)
	at org.apache.lucene.store.IndexOutput.writeBytes(IndexOutput.java:40)

	at org.apache.lucene.index.ConcurrentMergeScheduler$MergeThread.run(ConcurrentMergeScheduler.java:240)
------------------------------------------------------------------------
and this is happening quite frequently, although I am not able to reproduce it on demand,
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?
