>
> Key: QPID-5791
> URL: https://issues.apache.org/jira/browse/QPID-5791
> Project: Qpid
> Issue Type: Bug
> Components: Java Broker
> Affects Versions: 0.26, 0.28, 0.29
> Reporter: Keith Wall
> Assignee: Alex Rudyy
> Priority: Minor
> Fix For: 0.29
>
>
> The JsonStore currently does not synchronise its update method, meaning that it is possible for an #create (or #detele) to race with an #update and end with the following stack trace.
> This problem can only affect users of split configuration/message store (introduced by QPID-5087) where the configuration store is of type JSON. This has only become default for 0.30.
