Description

Thrift file: ( client to java Server )

service myService {

oneway void info ( 1:i32 server_id )

}

When I make a request with info, on the java server I get this error:
22:16:12.553 [pool-3-thread-5] ERROR o.a.thrift.server.TThreadPoolServer - Error occurred during processing of message.
java.lang.NullPointerException: null

On line 34 of ProcessFunction we have: result.write(oprot); but result is null, becouse when the func is oneway, getResult's response is always null
TBase result = getResult(iface, args);
oprot.writeMessageBegin(new TMessage(getMethodName(), TMessageType.REPLY, seqid));
result.write(oprot);

getResult funcion is:
public info_result getResult(I iface, info_args args) throws org.apache.thrift.TException

{ iface.info(args.server_id); return null; }

instead without oneway it is:
public info_result getResult(I iface, info_args args) throws org.apache.thrift.TException

{ info_result result = new info_result(); iface.info(args.server_id); return result; }
