Channel.getState() returning false indicates a problem either with the
communications or with the coordinator's preparation of the state.
Hmm...something I just thought of. We:
1) connect the channel
2) call Channel.getState()
3) if that returns false, block until we get a view so we can see if we
are coord. If not coord, throw an exception as getState() returning
false is an error condition.
There's a race between 2 and 3, i.e. getState() returns false but then a
merge happens and in 3 we find we are not the coord. Perhaps better is
to:
1) connect the channel.
2) block until we get a view
3) if we aren't coord, call channel.getState(), throw exception if
returns false
Don't particularly see how any of the above relates to WebLogic though.

do we have a problem with state transfers on WebLogic?
