It is very likely to be related to the way envelope are rounded.
Current GeoTools rounding mode is "nearest integer" (Math.round). They were
recent discussion about changing the rounding mode to "lower integer"
(Math.floor) for the first row/column, but it would probably have accentuated
the behavior you are observing.
A possible experiment may be to change the rounding mode in
GeneralGridRange(Envelope) constructor - this constructor already has a quite
large discussion about rounding more in the javadoc. It could be interresting
to
check if "higher integer" (Math.ceil) for the first row/column help.
