Description

DefaultFluentProducerTemplate

code:

producer = context.createFluentProducerTemplate();

future1 = producer.withHeader("action", "register").withBody(body1).asyncSend();
future2 = producer.withHeader("action", "register").withBody(body2).asyncSend();

These two subsequent calls produces with the default creation two calls with the same body - body2.
The cause is that it uses default processor supplier () -> this::populateExchange which is call lazily at the time of send and at that time the body property of DefaultFluentProducerTemplate is body2.
