It probably is, however in 2.1.0 the JSON-RPC plugin talked directly to 
internal rabbit objects like queues, and was thus susceptible to this 
bug. At some point (I don't remember exactly when) it was rewritten to 
talk to rabbit via the direct Erlang client (effectively 
AMQP-over-Erlang) and thus things should be rather more sanitised by the 
time JSON-RPC sees them. These days it should not need to call 
ensure_content_decoded() any more than a Java app would.

So I think the bug you're seeing is fixed by coincidence now. I 
recommend you upgrade.

Cheers, Simon
