Hello,

for people that get the "write error" issue with the console, i have an
explanation and a workaround:

Explanation:
-------------------
If you have a long initialization in the TestRunner class above 30 seconds,
you will get this message as the console doesn't appreciate long waiting as
soon as you clicked on Start.
The default and cached value for the idle time tolerance value is 30
seconds. After this 30 seconds, it cut the socket.

Work around:
--------------------
just expose as System variable the inactiveClientTimeOut variable in
ConsoleCommunicationImplementation.java code.
We are so able to change it to 300 000 (5minutes) by configuration.
No a beautiful solution - but not complex one.


cheers,
Olivier
