AMQ_SCHEDULER_ACTION_BROWSE returns incomplete list
I'm making good use of the ActiveMQ 5.6 scheduled message feature.
schedulerSupport="true" and my complete scheduled message list appears as
expected on the "Scheduled" page when I view usings the ActiveMQ admin
console.
I need to browse the list to delete messages so I've written some java code
that makes use of the AMQ_SCHEDULER_ACTION_BROWSE property.
This works OK but does not retrieve the complete scheduled message list.
Older scheduled messages are not returned at all but recent (last 24 hours)
submitted scheduled messages are returned correctly.
At first I thought messages were somehow being cached in memory so I
restarted ActiveMQ but I still just get back the recent messages created
today but not those visible on the admin console that were created a few
days before.
I have not yet determined the cut off point at which the messages are no
longer browsable.
Is the underlying KahaDb setup doing something odd?

A test case would be good.
The TTL should only be applied for the Message once its scheduled send
time arrives such that the newly sent scheduled message will time out
like any other message. Scheduled tasks should "time out" based on
their own scheduling criteria and not the TTL of the Message.

Yah, unless Tim or Gary know off hand why this is, I would say open a JIRA.
I am not seeing any logic in the code that would filter out messages for a
browse based on TTL.
It would be great if you could throw together a little unit test that shows
this and I can take a closer look. Take a look at this test for an example
of a unit test:

I can confirm that the deafult 3 hour expiration (timeToLive) value applied
to all messages by my template was causing the problem.
If I override and set expiration = 0 for the scheduled messages then they
are browsable.
Is there a JIRA required here?
Should ActiveMQ schedule browse action disregard expiration and not filter
out expired messages when browsing the scheduled message list?
Should scheduled messages always have expiration set to zero?

Maybe you can open a JIRA?

Might have the answer.
I'm pretty sure my scheduled messages are (incorrectly) being submitted
using a SpringJMSTemplate where timeToLive= 3 hours.
3 hours after submission they are no longer browsable using
AMQ_SCHEDULER_ACTION_BROWSE but they remain visible on the admin console
scheduled messages page and still behave correctly as scheduled messages.
