Øystein Grøvlen commented on DERBY-3254:
----------------------------------------

I do not understand the change to MasterController#startFailover.  It seems 
like handleFailoverFailure will be called in all cases now.  Also, exceptions 
thrown by handleFailoverFailure called from the try block, will be caught and 
passed to handeFailoverFailure by the catch block.  That seems a bit 
unnecessary.  I think the whole handling of ack, as it was in v4 of the patch, 
should be moved outside the try block.
