Re: ava.lang.AbstractMethodError: org.apache.thrift.ProcessFunction.isOneway

[Jens Geyer <je...@hotmail.com>]

Hi Avinash,

after doing a quick check over the java library I'm not quite sure whether 
this is a bug in the Thrift code or not. There are two declarations of 
isOneway(), both abstract. On the other hand, there are two occurences in 
the generator, where the missing overrides seem to be generated. The method 
is called only once, within ProcessFunction<I, T>.process(), exactly as your 
stack indicates.

I'd recommend that you try to provide a more complete, reproducible test 
case which wil help to track that down.

Not necessarily. It just means, that there some virtual method gets called 
but there is no override for it. The compiler is not necessarily able to 
detect that.

Hi all,
I think my older email did not reach.
I am getting following error. where should I look for possible cause.
AbstractMethodError should be compile time,  guess

That's usually a classpath/version problem. Make sure the jars you're
running against are the same as the ones you compiled against.
