The PRECONDITION_FAILED is because the queue has already been declared without x-message-ttl and when trying to declare it again with a x-message-ttl, the declare fails because the arguments of the declares are different. Try deleting the queue, then declare it with a int32 x-message-ttl.

It looks like rabbitmq doesn't know how to parse values tagged with 'i' (unsigned int32) and it crashes the connection. The java library sends a signed 32 bit integer from the example.
This should work for you:
args["x-message-ttl"] = int32(900000)

Yes, sorry, just read up on that now (https://jira.springsource.org/secure/attachment/20196/AMQP-265.txt).
Works like a charm after deleting the existing queue.
Thank you for making this lib and thank you for helping! ๐

It's likely a bug in the table tags used during serialization. I went strictly from the 0.9.1 spec, but there were some changes between 0.8, 0.10, 0.9 and 0.9.1. The server may expect a different tag for the value and closed the connection (the 501 error). Your server log should show what exactly went wrong.
What server and version are you using?

RabbitMQ 3.0.2, Erlang R15B02.
When running with uint32 I get the following in the log:

I also tried with signed int as suggested but it complains with a PRECONDITION_FAILED again.
"PRECONDITION_FAILED - inequivalent arg 'x-message-ttl'for queue 'soamon.requests-dead' in vhost 'soamon': received the value '900000' of type 'signedint' but current is none"
