Kie REST API client does not work. Pasting the relevant error message (see also the attached perfcake.log):

Caused by: com.sun.xml.bind.v2.runtime.IllegalAnnotationsException: 2 counts of IllegalAnnotationExceptions
java.util.Map is an interface, and JAXB can't handle interfaces.
	this problem is related to the following location:
		at java.util.Map
		at private java.util.Map org.kie.services.client.serialization.jaxb.impl.process.JaxbWorkItem.parameters
		at org.kie.services.client.serialization.jaxb.impl.process.JaxbWorkItem
java.util.Map does not have a no-arg default constructor.

To reproduce:
1.) Download BPMS 6 ER5 and merge it with EAP 6.1.1 distribution.
2.) Add user guest, password guest into EAP config files:
application-users.properties:  guest=b5d048a237bfd2874b6928e1f37ee15e
application-roles.properties:  guest=kie-user,admin
3.) Setup datasource for BPMS, I used PostgreSQL. Make sure the db is empty before the test. Do not use the default H2.
4.) Start the server and go to http://localhost:8080/business-central.
5.) Clone repository git://git.app.eng.bos.redhat.com/bpms-assets.git to your BPMS installation.
6.) Build&Deploy a project bpms-perf from the bpms-assets.git repo.
7.) Make sure you can run REST API command POST on address:
http://localhost:8080/kie-wb/rest/runtime/com.bpms.flood:bpms-perf:1.0.0.Final/process/com.bpms.flood.HumanTask/start
8.) Run the performance framework:
git clone git://git.app.eng.bos.redhat.com/jbossqe-process-flood.git
cd jbossqe-process-flood/bpms-6.x
./execute_scenario.sh -Dscenario=HumanTask_kieREST
(kieREST means that official kie REST client will be used)

This bug prevents to create complete performance report, because the REST API will be measured only by one REST client - HTTPSender class of PerfCake framework (in this case scenario HumanTask_pcREST).

My env:
BPMS 6 ER5
EAP 6.1.1
PostgreSQL 9.1.9
postgresql-9.1-902.jdbc4.jar
Comment 1 Marco Rietveld 2013-11-26 00:03:58 UTC 
Would you mind retrying this, but with the jaxb-impl 2.2.5 dependency, instead of the 2.2.4 version which is used in jbossqe-process-flood/bpms-6.x ? 

2.2.5 supports Maps, while 2.2.4 does not. 

mvn dependency:tree reports that jbossqe-process-flood/bpmns-6.x uses 2.2.4: 

[INFO] +- org.jboss.resteasy:resteasy-atom-provider:jar:2.3.7.Final:compile
[INFO] |  +- org.jboss.resteasy:resteasy-jaxb-provider:jar:2.3.7.Final:compile

Thanks!

Comment 2 Jiri Svitak 2013-11-26 11:10:42 UTC 
Thanks Marco,

You are correct. There were changes in dependencies hidden to my sight. I have changed my dependency management to use jbpm bom to fix the issue:
http://git.app.eng.bos.redhat.com/jbossqe-process-flood.git/commit/?id=a933096c753d5733b6c589d884c5f711488a9495

Now it works. Closing the BZ.
