While a valid concern, I personally disagree that this is sufficient
reason to keep the "silently broken" behaviour, which is our status quo.
That said, as I am not going to implement the change, I am not the one
you need to convince.

This is certainly a possible solution. Another would be to make them
build-depend on gcj-jdk, if they are truly java5 compatible. I believe
gettext is mostly in the latter category - my guess is that they have
not touched those bindings considerably in many years.
My concern with gcj-jdk implementing default-java is that it leads to
silent breakage because gcj-jdk is stuck in ("almost") Java5 support
while Debian is moving to OpenJDK-8 with lambda functions, tons of new
classes etc. This breakage is /not/ discovered by us, but by our end
users that consumes ports without OpenJDK support and I think that is
the wrong signal to send to our users.
Thanks,
