> RoleDisseminator fails to check for possible null password
> ----------------------------------------------------------
>
> Key: DS-1569
> URL: https://jira.duraspace.org/browse/DS-1569
> Project: DSpace
> Issue Type: Bug
> Components: DSpace API
> Affects Versions: 3.0, 3.1
> Reporter: Tim Donohue
> Assignee: Mark H. Wood
>
> If a single user in DSpace happens to have a "null" password (e.g. external
> authentication system is being used), and the RoleDisseminator is called with
> "emitPassword=true", then a NullPointerException will occur.
> For example, passing the "passwords=true" flag to the AIP Packager will
> result in a NPE if a single user has a null password:
> dspace packager -d -a -t AIP -e [admin-email] -i 10673/0 -o passwords=true
> [email protected]
> Here's the resulting error message:
> org.dspace.content.crosswalk.CrosswalkInternalException: Failed to export
> Roles via packager (see wrapped error message
> for more details)
