[jira] [Created] (QPID-5791) JsonStore implementation does not
synchronise update allowing for race with create/delete
Keith Wall created QPID-5791:
--------------------------------
Summary: JsonStore implementation does not synchronise update allowing for race with create/delete
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: Keith Wall
Priority: Minor
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 where the configuration store is of type JSON. This has only become default for 0.30.
