ServiceReplica#leave throws NullPointerException #12

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. instantiate 4 service replicas 
2. send ordered messages
3. call ServiceReplica#leave to teardown my test cases

What is the expected output? What do you see instead?

I would expect the replica to be removed from the test set. My idea is to call 
this for each replica so that I can start new replica servers with different 
business logic (for other test cases).

What version of the product are you using? On what operating system?

bft-smart 0.8, Ubuntu Desktop 13.04 as well as Ubuntu Server 13.04

Please provide any additional information below.

A short investigation showed that the ServiceProxy within the generated 
Reconfiguration Object is never initialed (it was commented out in the 
constructor, the new (?) connect method is not called)
