JMS client: node binding not created for topic node

When creating a topic (an exchange in qpid terminology) with x-bindings within node: scope, the binding is not created. See this simple reproducer:

qpid-config add queue q
export CLASSPATH=$(find "/usr/share/java/" -name '*.jar' | tr '\n' ":")
cd /usr/share/doc/qpid-java-0.14/examples
./run_example.sh org.apache.qpid.example.Spout --content="msg1" "ex/key;{ create: always, node: { type: topic, x-bindings: [

{ exchange:'ex', queue: 'q', key: 'key' }

]}}"

qpid-config exchanges -b then shows no binding from 'ex' exchange.

Simple patch to be attached.
