> 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;
>       }
