--------------------------------------------------------------
In jBPM5 you can't manually suspend a process. Processes are automatically suspended when, during its execution, they reach a wait-state (nothing else to execcute). This could be the case of async Tasks, Events, Rule Execution, etc. Resuming the process execution depends on what is the process waiting for: 
* ksession.signalEvent() -> if the process is suspended in a event
* ksession.getWorkItemManager().completeWorkItem() -> if the process is suspended in an async Task
* using Human Task Client API -> if the process is suspended in a Human Task
* ksession.fireAllRules() -> if the process is suspended in a Rule Task node.

Regarding your last question, why do you need startProcess() to return immediately? If what you need is the id of the process, then you can separate startProcess() in:
1. ksession.createProcessInstance() -> creates an instance and persists it in the db
2. ksession.startProcessInstance() -> actually starts the execution of the process instance.
