Is it possible: Stop large message already in progress?
We have a requirement where we must prioritize messages prior to placing them
in an ActiveMQ queue. However, we are variable bandwidth connection that
could degrade during application operation.
If we are sending a large object, say an image of 5 MB, and our bandwidth
degrades during the send, we need to be able to stop the currently
in-progress ActiveMQ message so that a higher priority, smaller message can
go first. We can place the image back into the queue later.
Is there a way to stop a message that has already started down the line via
JMX or directly?

the answer may be in an inactivity monitor. However I think what you need is
the existing behavior that is only aware of complete message transfer rather
than a message in progress. See some of the detail in
https://issues.apache.org/activemq/browse/AMQ-2088 which makes the
inactivity monitor aware of a transfer that is in progress.
For you, I think this new behaviour (from 2088) needs to be optional. Also
