Java.lang.ClassNotFoundException: long. JpdProxy call

Question

I'm migrating a Weblogic Integration 8.5 sp5 application to Weblogic Integration 9.2 MP1. The application makes call to different JPDs through JPDProxies in java service class as follow:
WorkflowRequest wfAdmissibility = (WorkflowRequest)JpdProxyImpl.create(WorkflowRequest.class,serviceUri,null,Boolean.FALSE)
try {
wfAdmissibility.clientRequest(new Long(activity.getId()), command, new Long(userId));
WfData wfdata = wfAdmissibility.clientReturn();
return wfdata;
} catch (Exception e) {
log.info("exception", e);
throw new WorkflowException(e);
I deploy my application without problems on a cluster containing one member which is a managed server.
Everything works fine until the jpd is called at runtime. With some debug I identify that the error occurs when calling the clientRequest method in the preceding code exemple. I changed the parameters of the method from type long to Long but it's exactly the same error. I now think of a classLoader problem but I'm not familiar enough with those things. I really can't find solutions nor documentation (every doc about jpdProxy is for WLI 8.15 not 9.2).
Here is the beginning of the stack trace:
