Re: NPE Within IndexWriter.optimize (Solr Trunk Nightly)
Uwe, Mike, I downloaded the nightly build by visiting the wiki: http://wiki.apache.org/solr/FrontPage ... and then clicking on "Download newest Solr nightly build here" http://hudson.zones.apache.org/hudson/job/Solr-trunk/lastSuccessfulBuild/artifact/trunk/solr/dist/ The exact file I download yesterday was: http://hudson.zones.apache.org/hudson/job/Solr-trunk/lastSuccessfulBuild/artifact/trunk/solr/dist/apache-solr-2010-05-24_08-05-13.tgz (no longer exists). I have no patches or mods added. The CHANGES.txt file in the download includes this: ~ $Id: CHANGES.txt 945897 2010-05-18 21:30:41Z hossman $ == 4.0.0-dev == Versions of Major Components - Apache Lucene trunk Apache Tika 0.6 Carrot2 3.1.0 ~ Did I fetch the wrong version? If so, where can I grab the (1.5.x) nightly builds? Mike, thanks for the CheckIndex suggestion. Shall run that once I've confirmed which version I'm running.

NPE Within IndexWriter.optimize (Solr Trunk Nightly)
Hi, I'm using the latest nightly build of solr (apache-solr-2010-05-24_08-05-13) and am repeatedly experiencing a NullPointerException after calling delete, commit, optimize. Stack trace below. The index is ~20Gb. I'm not doing Lucene/Solr core development - I just figured this was a better place to ask given that this was a nightly build. Any observations that would help resolve?
