   my tests are currently all in Python as we do external tests only.
   most of it was included in https://issues.apache.org/jira/browse/ARTEMIS-3461.
   here is the useful part of that list.
   
   {code:java}
   123
   'hello'
   1e30
   True
   False
   [4,5,6,'hello']
   [4,5,6]
   {"a":4,"b":5,"c":6,"d":'hello'}
   [4,5,6,["abc","def","ghi"]]
   [4,{"a":5,"b":5,"c":5},6]
   {"a":[4,5,6,'hello'],"b":2}
   {code}
   
   there are many encodings for primitive types in amqp. but the representations for these are all handled by the qpid proton library. notable exceptions are the decimal types which cannot easily be understood by java. qpid shows these as e.g. "org.apache.qpid.proton.amqp.Decimal32@_nnnnn_" where _nnnnn_ is the internal value as integer. also homogeneous arrays (all elements have same type) are not very well supported. luckily my use-cases do not involve either of these.
