Code generator: return statement in void method

[kabl]

The code generator generates following code:

  public void setGreeting(Utf8String s) throws InterruptedException, ExecutionException {
    Function function = new Function<>("setGreeting", Arrays.asList(s), Collections.emptyList());
    return executeSingleValueReturn(function);
  }

The return statement is not allowed.

Contract

contract hello {
    string greeting;

    function setGreeting(string s){
        greeting = s;
    }

    function getGreeting() constant returns (string s){
        s = greeting;
    }

    function killMe(){
        suicide(msg.sender);
    }
}
