Wrong set of property types.
Issue/Introduction
Resolution
When receiving u32 datatypes from RV, use long datatypes in event properties as RV returns long if you get a field using the TibrvMsg.get() method. This is documented on the RV side (See Reference section below). When you add/update a field in the RV message using the TibrvMsg.updateU32() method on the sender and at the listener, try to get the field using the TibrvMsg.get() method. It will return a long value.
Additional Information
Refer to the RV documentation (tib_rv_java_reference, the figure detailing "Wire Format to Java Datatype Conversion Matrix") for the TibrvMsg.get() API.
