Oups, pressed enter too fast. Description:

if message A contains message B, which contains message C

then message A will have the wrong size for message B, because the calculation 
of the
size of message B will forget the byte for the tag and the byte for size of 
message C.

Need to be solved by first writing B to a tempStream, then measuring its real 
size.

The change is:

public function writeMessage(fieldNumber:int, value:Message):void {
        writeTag(fieldNumber, WireFormat.WIRETYPE_LENGTH_DELIMITED);
        var tempStream:ByteArray = new ByteArray();
        value.writeToDataOutput(tempStream);
        tempStream.position = 0;
        writeRawVarint32(tempStream.length);
        output.writeBytes(tempStream,0,tempStream.length);
      }

instead of

public function writeMessage(fieldNumber:int, value:Message):void {
        writeTag(fieldNumber, WireFormat.WIRETYPE_LENGTH_DELIMITED);
        writeRawVarint32(value.getSerializedSize());
        value.writeToCodedStream(this);
      }
