The reason I opted for supporting null values was that the RPC system already supported null return values for synchronous RPCs, for example `Integer foobar()` could return `null` w/o problems. Moreover, it is the more general solution. As a drawback it comes with all the problems null values in the Java world cause. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
