>             Project: Qpid
>          Issue Type: Bug
>          Components: Broker-J
>    Affects Versions: qpid-java-6.1, qpid-java-broker-7.0.0, 
> qpid-java-broker-7.0.1
>            Reporter: Keith Wall
>            Assignee: Keith Wall
>            Priority: Minor
>             Fix For: qpid-java-broker-7.1.0
>
>
> As an authenticated user, putting (HTTP PUT) a user preference to the store 
> when using a configuration store backed by BDB (or JDBC), fails with a stack 
> trace like the following.  The store exception would cause the Broker to 
> fail.   A restart would restore normal service.
> The normal use-case for preferences is the persistence of queries within the 
> web-management console.  The console uses POST operations so it unaffected by 
> this defect.
