[january-dev] Januart Datasets and Java 8

[Jonah Graham <jonah@xxxxxxxxxxxxxxxx>]

(Changed subject, was Re: [january-dev] January 1.0 released!)

Hi Peter,

I think this warrants further discussion. There are reasons I would
encourage Java 1.8:
- Not supporting Java 8 increases barriers to contributors (two ways,
1 not being able to use "all" Java features, 2 tooling and setup makes
it more complicated*)
- Java 6 & 7 of EOL
- The IDataset, originally part of the API plug-in was 1.7 or greater
since DAWNSci initial import, the 1.8 was put in place in April.
Although some other bundles had lower reqs, having any dep be 1.8,
this essentially meant that everything was 1.8 in practice.

So, when I set the 1.8 across the range, it was because of these
reasons, the lack of earlier discussion was due to the implicit
assumption on my part due to the last reason, so thank you for raising
it now to make sure it is discussed fully. (You did point this out
earlier[1], but I misunderstood the meaning of the comment at the
time).

There is one strong reason against 1.8 (or at least delaying the move to 1.8):
- A specific/known potential consumer of January datasets is stuck
with Java < 1.8

Peter, please let me know your thoughts and what I may have overlooked.
Thanks,
Jonah
