There should be method signatures (if Java allows this) and unit tests for:

RemoteServer.call("METHOD")      // no argument

Also, RemoteServer.call("METHOD", null) should not trigger the event-based code path, treating null as an Event. Such a call should either signal an error or behave like the above signatures.

Initial support is available in: 9a4cd505a9eba2939637623b55b7713cde7eda49

The client-side API now supports parameterless calls such as:


The server-side API needs a bit of discussion, e.g., whether an additional type of callback interface would be handy (or not) given the fact that event handlers already have the required semantics for this case (primarily: no return value). As an alternative, one may also just use the existing callback interfaces and just return null.

Sorry, I cannot find the new signatures. Did your commit include all changes?

Sebastian: I looked at this once and it seemed fine (if I remember correctly). Would you rather first finish everything or can you merge the @RemoteServer part?
