Description

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)

• is depended upon by: ACCUMULO-2410 TServerUtils no longer needs to catch NPE as a thrift bug workaround
• is duplicated by: THRIFT-1511 Server with oneway support ( JAVA )
