Process definition is not persisted in standalone jBPM3

Issue

I'm using the following code trying to deploy the process definition in a par file

fileInputStream = new FileInputStream(resourceLocation);
ZipInputStream zipIpInputStream = new ZipInputStream(fileInputStream);
ProcessDefinition processDefinition = ProcessDefinition.parseParZipInputStream(zipIpInputStream);
jbpmContext.deployProcessDefinition(processDefinition);

right after calling above, I can see the new process definition by calling the following

List<ProcessDefinition> lst = jbpmContext.getGraphSession().findAllProcessDefinitions();

However, I could not see it in either database jbpm table or EAP jbpm console.
