Exception Propagation

• How can a Java runtime exception be properly marshalled and propagated to the consumer? Common Questions:
• Is there a generic marshaller that can propagate Java exceptions?
• If not, how can I implement a generic interceptor for my exceptions?
• Is it better to throw the exception or have an error status return payload?
• What happens when you throw an uncaught exception and not having called onComplete/onError callbacks?
• Metadata = across process
