TransportType.getEnvelopeType() -> java.lang.NoSuchMethodError ?

I'm puzzled by the error below.  I simply called iosession.write(<some bytebuffer>) - there are no filters in the chain by the way.

 

Took me forever to find this too by the way; I think it's a terribly bad idea to not propagate exceptions back up the callstack.

 

(using mina 0.9.4)

In this case, I agree. Exceptions that occur synchronously should be  
propagated. There's also a good argument for the unified place to  
receive all exceptions though :)

Do you have an older MINA version on your classpath?
