Not possible to create pretty JSON from headers.

[carlbenson]

AMQP.BasicProperties.getHeaders() returns a Map<String, Object> where the strings are of type LongStringHelper.ByteArrayLongString that is a private internal class which makes it impossible to write custom serializers for this class. Using Google Gson for instance, always inserts a "bytes": key before the value. While it is easy to write a serializer that converts the resulting byte[], I'd like to have the string value only without the "bytes": key.

In short, how can I produce a regular Java string out of LongStringHelper.ByteArrayLongString?

ByteArrayLongString#toString?

It's private.

@carlbenson toString will be a part of the LongString interface in 3.6.0.

@carlbenson for now, it should be possible to use getBytes (already part of the interface) and produce a string from that, using UTF-8 as encoding.
