Date Sat, 14 Nov 2009 01:29:39 GMT

    [ https://issues.apache.org/jira/browse/SOLR-1563?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12777790#action_12777790

Hoss Man commented on SOLR-1563:
--------------------------------

These stack traces demonstrate similar NPE exceptions when attempting to upgrade from 1.3
to 1.4 using the example schema provided in 1.3...

steps to reproduce...
* using 1.3...
*# cd example && java -jar start.jar
*# cd example/exampledocs && java -jar post.jar *.xml
*# note these urls work and return meaningful data...
*#* http://localhost:8983/solr/select/?q=SP2514N
*#* http://localhost:8983/solr/admin/luke?id=SP2514N
*# shutdown the 1.3 port
* using solr 1.4, point it at your 1.3 example solr home dir...
*# cd example && java -Dsolr.solr.home=../../1.3_solr/example/solr/ -jar start.jar
*# note that solr starts cleanly with no errors
*# verify that this URL displays the solr home you expect, in the 1.3 example directory...
*#* http://localhost:8983/solr/admin/
*# note that these URLs fail with the errors listed below...
*#* http://localhost:8983/solr/select/?q=SP2514N
*#* http://localhost:8983/solr/admin/luke?id=SP2514N

> Multiple reports of NPEs when using Solr 1.4 - so far these all seem to relate to getting
a null returned by Fieldable.stringValue when it isn't expected or accounted for.  Thread
where this was initially discussed...
