Thanks! If that works, it is perfect. However, my first attempt isn't
making any difference. Here is what I have:
(defmethod print-dup
com.rabbitmq.client.impl.LongStringHelper$ByteArrayLongString [o w]
(print-ctor o (fn [o w] (print-dup (String. (.getBytes o)) w)) w))
(defn spit-messages
"Write out the messages in the given seq."
[messages dest]
(print-dup
(for [[metadata ^bytes payload] messages]
{:header metadata :payload (String. payload)})
dest))
but it still prints it out to the file with #<ByteArrayLongString PLUGIN2>.
Did I miss something?
