Valentin Kulichenko commented on IGNITE-8154:
---------------------------------------------

[~antkr], please replace `U.warn` with `U.error` so that the whole stack trace 
is logged in case of exception.

In the test, you should avoid loops that can possibly never finish, like these 
ones:
{code}
while(lsnrExceptions.isEmpty())
    Thread.sleep(200);
{code}
Instead, you should have a {CountDownLatch} that is counted down from the 
exception listener. Test itself should then call `await()` with a timeout and 
assert that it returns `true`.

> JMS API allows to provide custom {{ExceptionListener}} that is invoked when 
> an exception occurs within JMS queue/topic. Currently, {{JmsStreamer}} 
> doesn't use this in any way which creates two issues:
> * If there is an exception, it's lost and not even logged.
> * User can't provide their own listener.
