Hi,

(Our system: Dspace 5.5,  xmlui + mirage 2, Oracle 11, CentOS)
 
We are testing the activation of the authorities control  and when executing 
'dspace index-authority' we encounter the following error
 

> Retrieving all data
> Initialize org.dspace.authority.indexer.DSpaceAuthorityIndexer
> Exception: null
> java.lang.NullPointerException

How can we find the origin of this? We have reviewed the logs and can't find 
any clue.

We have also verified that we don't have discoverable items without authors. 
Apart from some in workflow queue



Thanks in advance
Javier
