Description of problem:
Querying Active Collections REST (/overlord-rtgov/acm/query) can't deserialize input object (FUSE 6.1 + FSW 6.1DR2):
Could not find message body reader for type: class org.overlord.rtgov.active.collection.QuerySpec

Version-Release number of selected component (if applicable):
2.0.0.Beta2-redhat-1

How reproducible:
always

Steps to Reproduce:
1. Install Fuse 6.1 + FSW 6.1 DR2

2. Run Fuse and install features like switchyard, switchyard-bean, switchyard-soap
using features urls
features:addurl mvn:org.switchyard.karaf/switchyard/2.0.0.Alpha2-redhat-1/xml/features
features:addurl mvn:org.switchyard.karaf/switchyard/2.0.0.Alpha2-redhat-1/xml/core-features

3. Install features like rtgov-all, rtgov-client, rtgov-switchyard
using features url
features:addurl mvn:org.overlord.rtgov/overlord-rtgov-features-fuse6/2.0.0.Beta2-redhat-1/xml/features

4. Configure security settings for overlord-rtgov. It's little bit tricky for me, so I have copied/merged it from /etc dir from installation of Fuse 6.1 + community Rtgov 2.0.0.Beta3

5. Send some proper POST request to http://localhost:8181/overlord-rtgov/acm/query e.g.:
Content-Type: application/json
{"collection":"ServiceResponseTimes","maxItems":0,"truncate":"Start","style":"Normal","predicate":null,"parent":null,"properties":{}}


Actual results:
Server returns response "Error 400 Could not find message body reader for type: class org.overlord.rtgov.active.collection.QuerySpec of content type: application/json"
