I agree that /etc/.java looks suspicious but I'm not sure if it's worth
the potential disruption. I guess we could consider supporting two
locations. If the new location exists then we use it; if only the old
location exists then use that. That would at least ensure that existing
system preferences wouldn't get lost when you move to jdk8 and it would
mean that over time that system preferences would be stored in the new
location. This approach would of course run into problems if there were
a mix of jdk versions on a system -- ie: run something with jdk8 on a
new system and it stores the preferences in the new location. Run it
again with jdk7 or older and it will appear that the preferences have
been lost. That said, I believe that the intention with preferences is
that the format could evolve over time and so having a older jdk read or
update the system preferences that were created by a newer jdk might not
be a big concern.
I would be more cautious with user preferences as my guess is that they
are used more than system preferences (because system preferences need
privileges to create). I also think that ~/.java/.systemPrefs isn't a
major concern (unlike /etc/.java).
