> Key: QPID-4441
> URL: https://issues.apache.org/jira/browse/QPID-4441
> Project: Qpid
> Issue Type: Bug
> Components: Java Broker
> Affects Versions: 0.18
> Reporter: Robbie Gemmell
> Assignee: Robbie Gemmell
> Priority: Blocker
> Fix For: 0.19, 0.20
>
>
> The queue declare arguments are lost during v5 -> v6 store schema update for
> the optional bdbstore. This will present itself in a variety of ways, such as
> a DLQ losing the marker argument used to prevent chained DLQ creation, and
> also in Priority and Sorted queues becoming regular queues.
> As part of the schema update, the old FieldTable binary encoding for the
> queue arguments is transitioned to a property within the larger JSON
> ConfiguredObject encoding. This process makes use of an intermediate
> FieldTable to which it does an addAll() based copy of the original FieldTable
> and then potentially adds a new description argument. This addAll() fails to
> copy the previous properties due to a defect in the method, wherby the source
> FieldTables lack of use after creation from encoded bytes means they have yet
> to be decoded and this is in effect mistaken as it being an empty FieldTable.
