Bryan Duxbury commented on THRIFT-1447:
---------------------------------------
Hm, this is interesting. It must have gotten changed when we refactored this
part of the code a while ago, otherwise oneway functions would never have
worked. We probably need to be smart about this - if a non-oneway method
returns null, it should be an exception.

> Key: THRIFT-1447
> URL: https://issues.apache.org/jira/browse/THRIFT-1447

> Affects Versions: 0.8
> Environment: Mac OS X Lion 10.7.2
> java version "1.6.0_29"
> Java(TM) SE Runtime Environment (build 1.6.0_29-b11-402-11M3527)

> lines 31-36 of ProcessFunction.class:
> iprot.readMessageEnd();
> TBase result = getResult(iface, args);
> oprot.writeMessageBegin(new TMessage(getMethodName(), TMessageType.REPLY,
> seqid));
> result.write(oprot);
> oprot.writeMessageEnd();
> oprot.getTransport().flush();
> problem in case where result == null;
> getResult(..) for my "oneway" method(generated code) :
> @Override
> protected org.apache.thrift.TBase getResult(final I iface, final
> processUA_args args) throws org.apache.thrift.TException {
> iface.processUA(args.appIdNames, args.platform);
> return null;
> }
> so it always return null, and crash on 34 lines(ProcessFunction.class)
