A flaw was found in AMQ Online before 1.5.2, where injecting an invalid field to a user’s address space configuration of the user namespace puts AMQ Online in an inconsistent state. In this inconsistent state, the AMQ Online components do not operate properly. For example, the failure of provisioning and the failure of creating addresses may occur. However, this issue does not impact already existing messaging clients or brokers.
The user can work around the issue by repairing the resource and removing the invalid (top-level) field.
