> Preferences service throws ClassCastException
> ---------------------------------------------
>
> Key: FELIX-411
> URL: https://issues.apache.org/jira/browse/FELIX-411
> Project: Felix
> Issue Type: Bug
> Components: Preferences Service
> Reporter: Angelo van der Sijpt
> Assignee: Carsten Ziegeler
>
> The preferences admin throws a ClassCastException when writing its cache. The
> exception is
> java.lang.ClassCastException: [Lorg.apache.felix.prefs.PreferencesImpl;
> cannot be cast to org.apache.felix.prefs.PreferencesImpl
> at
> org.apache.felix.prefs.impl.PreferencesManager.save(PreferencesManager.java:179)
> ...
> This seems to have to do with the implementation of PreferencesImpl: in its
> constructor, all preferences are loaded. The system preferences are stored,
> 61 this.systemTree = prefs[i];
> but the user preferences are stored incorrectly:
> 63 this.trees.put(prefs[i].getDescription().getIdentifier(), prefs);
> The full array of prefs is stored, not just prefs[i]; this causes the
> classcastexception.
> A possible fix could be
> 63 this.trees.put(prefs[i].getDescription().getIdentifier(), prefs[i]);
