-----------------------------------

Creating a unit test is a good place to start.

>             Project: ActiveMQ
>          Issue Type: Bug
>          Components: Broker
>    Affects Versions: 5.14.4
>         Environment: Windows 7, 64 Bit, Java 1.8.0-101

> I use expireMessagesPeriod="100" for topics and the timestamp-plugin with a TTL of 1s.

> If I publish messages the "Pending Queue Size" of a offline duracle subscriber never
reaches 0 (in real life it increases steadily).
> Steps to reproduce:
> a) Start a clean/fresh activemq 5.14.4 broker instance with the attached activemq.xml
configuration (or adapt the default configuration to use expireMessagesPeriod and timeStampBrokerPlugin
- see also patch file)
> b) Use "ant consumer -Durl=tcp://localhost:61616 -Dtopic=true -Dsubject=MYSUB -Ddurable=true"
to create topic and durable subscriber
> c) Press ctrl+c to exit the consumer - and create the offline durable subscription
> d) Publish 2000 message via "ant producer -Ddurable=true -Durl=tcp://localhost:61616
-Dtopic=true -Dsubject=MYSUB"
> Expected result:
> "Pending Queue Size" of the corresponding Offline Durable Topic Subscriber should reach
0 (at least after a few seconds)
> Actual result:
> "Pending Queue Size" shows a value like 1752 and never decreases (see attached screenshot).
> Please let me know if you are able to reproduce the problem and if/how I can contribute.
