Scott Hanrath commented on DS-421:
----------------------------------
Fair enough. I think it would be helpful if the documentation was more
explicit. It was unclear enough to me that I went back through the code, which
is where I ran into solr.metadata.item.X. Since those properties are at least
present in the SolrLogger code (if no where else), I'm not sure saying the
fields are "not being used in the statistics package" is totally accurate
(though that edit is better than what was there before, saying that all fields
were indexed).
FWIW, I was able to use the 1.6rc SolrLogger code to index fields specified
using the solr.metadata.item property (so long as they are unqualified and
included, along with a corresponding field_search field, in the solr
schema.xml). From my perspective, I would suggest either the feature be
removed from the code or be documented and kinks like this bug worked out.

> Key: DS-421
> URL: http://jira.dspace.org/jira/browse/DS-421
> Project: DSpace 1.x
> Issue Type: Bug
> Components: DSpace API
> Affects Versions: 1.6.0
> Reporter: Scott Hanrath
> Priority: Minor
>
> Setting a solr.metadata.item.X property to an unqualified field (e.g.,
> dc.title rather then dc.title.alternative) generates an exception in
> SolrLogger.post on item view. The ArrayIndexOutOfBoundsException appear to
> prevent Solr from logging the event.
> The stacktrace from the logs is:
> java.lang.ArrayIndexOutOfBoundsException: 2
> at org.dspace.statistics.SolrLogger.post(SolrLogger.java:216)

> This is similar to DS-419 in that a metadata field like 'schema.element' is
> being split into an array and the methods is then trying to access
> non-existent 3rd element of the array (i.e., array[2], representing the
> qualifier) without checking the array length first.
