Eclipse Vert.x gRPC server does not limit the maximum message size
In Eclipse Vert.x version 4.3.0 to 4.5.9, the gRPC server does not limit the maximum length of message payload (Maven GAV: io.vertx:vertx-grpc-server and io.vertx:vertx-grpc-client). 




This is fixed in the 4.5.10 version. 




Note this does not affect the Vert.x gRPC server based grpc-java and Netty libraries (Maven GAV: io.vertx:vertx-grpc)
