Generics and wildcards

Not really a bug but a proposal of improvement:

Example:

ksession.startProcess("myprocess", Collections.singletonMap("myParam", "paramValue"));
-> Then Eclipse displays an error: "The method startProcess(String, Map<String, Object>) in the type ProcessRuntime is not applicable for the arguments (String, Map<String,String>)"

The signature of startProcess should be instead:
ProcessInstance startProcess(String processId, Map<String, ?> parameters);
