Re : poll VmPipe

[Edouard De Oliveira <do...@yahoo.fr>]

Don't know the code underneath VmPipe but is it possible to quickly rewrite it using blocking queues thus using new JDK abilities and reducing the codebase as seems to suggest Emm ?

Kind of mixed approach to please everyone :)

Well, if you just use VmPipe to unit test your deployed networked development, then I think that the potential improvement you may gain from avoiding an encoding/decoding call is irrelevant. More than that, I would expect my unit test to behave as the real program works, ie using the sockets instead of a fake communication inside the JVM.

AFAIR, the base idea was to eliminate the need to use sockets to exchange data between two threads in the same JVM. Blocking queues are ok for such purpose those days, no ?

Good idea, but does it's really hurting anyone to delete the whole
thing ? :)

That's a pretty good idea ! We have the Tennis sample, it would be 
worthly to rewrite it using queues to see what it brings (and it was 
Julien's idea, btw)
