The effect of transaction context on non-durable subscribers

A non-durable subscriber can only be used in the same transactional context (for example, a global transaction or an unspecified transaction context) that existed when the subscriber was created. A non-durable subscriber is invalidated whenever a sharing boundary (in general, a local or global transaction boundary) is crossed, resulting in a javax.jms.IllegalStateException with message text Non-durable subscriber invalidated on transaction boundary.

For example, in the following scenario the non-durable subscriber is invalidated at the begin user transaction. This is because the local transaction context in which the subscriber was created ends when the user transaction begins

...
create subscriber
...
begin user transaction - 
...
complete user transaction - 
...
use subscriber
...

If you want to cache a subscriber (to wait to receive messages that arrived since it was created), then use a durable subscriber (for which this restriction does not apply). Do not cache non-durable subscribers.
