Hi,
When ClientNotifForwarder starts, its first communication with
ServerNotifForwarder is to get clientSequenceNumber, then starts
LinearExecutor to execute the fetching job. If reconnection happens
during this communication, a new thread will be started by the
reconnection to do fetching job too, that's why the test got
"java.lang.IllegalArgumentException: More than one command "
I have verified the class ClientNotifForwarder to make sure no other
place would start a new job.
It is difficult to have a regression test to reproduce this bug, it is
all related to an internal function. I had to add code temporally into
the implementation to make the reconnection happen during this first
communication, in order to reproduce the bug and to verify the fix.
