I saw in the documentation the recommendation not to cache BytesXMLMessage objects, because they may be reused. I am usually extracting the data from it using getBytes() method, and pass it down to the next layer of my processing. Question: is it safe to pass that data array as is? Do I need to make a copy of it?

This is actually expected if you have no clients bound to the queue at the time of the replay. When clients bind, and as…
