     [ https://issues.apache.org/jira/browse/JS2-664?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Ate Douma closed JS2-664.
-------------------------

       Resolution: Won't Fix
    Fix Version/s:     (was: 2.2)

The Java Preferences back-end is going to be replaced with a new directly managed implementation so this specific problem will no longer exist.

> The User Browser was getting a NPE exception since the code expected "" to be returned from getPreferences().getValue with a default value provided:
>         String roleFilter = request.getPreferences().getValue("FilterByRole", "");
>         if (roleFilter == null)
>             roleFilter = "";
> See commit:
> http://svn.apache.org/viewvc?view=rev&revision=519196
> When a default value of "" is provided, it would be expected to get back "", not NULL
> However, NULL is being returned at times
> It seems that this only occurs with an Oracle database backend
