Description

When under system load, the Qpid JMS client doesn't handle scheduled message delivery correct - it delivers the message prior to the required time.

When running one request, the scheduling works correctly. The load to reproduce this isn't very high (i.e running about 5 of my job processes simultaneously seems to trip it up pretty quickly).

I have used different JMS Brokers with the same client code and the same problem occurs with both Brokers (see environment).

I am using Spring JMS Template to send the JMS message. The key piece of code is something like:

delayedDeliveryjmsTemplate.setDeliveryDelay(timeoutPeriod);
delayedDeliveryjmsTemplate.convertAndSend(queueName, timeoutMsg, (Message jmsMessage) -> {
{{ jmsMessage.setStringProperty(OBJECT_TYPE_FIELD, timeoutMsg.getClass().getSimpleName());}}
jmsMessage.setStringProperty(OBJECT_TYPE_FIELD, timeoutMsg.getClass().getSimpleName());
{{ return jmsMessage;}}
});

I realise you want more logging details but I'm unsure what would be best to log. Please let me know and I'll do so.
