Java 8 and Umple

[Kevin Brightwell]

Hello,

I've been working on updating some build structures for Umple (adding formal Ant tasks for umplec and umplei). In writing these tasks, I started using Java 8 constructs without thinking much about it.

I would like to purpose that the build chain for Umple be increased to the latest stable version of Java, Java 1.8. You can see feature changes here (this is a biased article, but it's OK).

In purposing this, the following would need to change:

1. Developers use Java 8 (if you use the auto-updater from Oracle, you'll already be there)
2. The cruise build server uses Java 8, OpenJDK does already have support for Java 8
3. Clients who use Umple need to have Java 8 to run umple
   

However, those who use generated code will not have to update (Umple still generates Java 1.6 classes AFAIK).

I'd appreciate any input on this.

Thanks,

Kevin

Hi,

I agree we need to move to Java 8. Oracle announced recently that they
won't update Java 7 beyond April.

We can do it over the next 3 weeks (say by March 15th, perhaps earlier,
but not instantly as I will need to upgrade on the server (a process which
turns out to be non-trivial as the CruiseControl system requires Java 6
still, and won't even work under Java 7 so there is some complex mechanism
to manage there).

Mac users haven't been pushed Java 8 yet by default, so we will need to
all update to it.

So don't do any patches or commits that require it for a while. If this
puts you in a bind, you are going to have to find a workaround.

And as for generated code, we want to be one step behind, so people can
make changes that generate Java 7, but don't generate Java 8 unique stuff
for a while.

Hi,

For Mac users, the knowledge base article actually says to download it from Oracle. So, while it's not automatic anymore (:(), it is expected that Mac folks download from Oracle. (Link)

As for putting me in a bind, I can also just hold off merging my patches until the systems are updated. They are not mission critical. The workarounds aren't worth the time (Java 8's Optional, and Streams are so nice).

For generated code, I agree whole-heartedly.

Thanks,

Kevin

Hi,

I have tested Java 8 on my Mac, and Umple seems to build fine.

The catch is that I can now no longer easily do a 'release' on Java 7,
since my Mac is 'converted', and it the Mac no longer makes it easily to
fluidly switch versions.

The next offial 'release' will be sometime in the coming couple of months,
and it will deliver jars in Java 8, which means we will have officially
cut over at theat time.

For those of you doing commits you should generally avoid committing jars
unless there is a key reason, but if you have to do so, you will need to
be aware that we are at Java 7 for now, and when given notice we will be
at Java 8, and you will have to be consistent with this.

If anyone has any problems cutting over to Java 8, let me know. It is best
to test now.

Hi,

I have tested all the mechanisms by updating to the latest Java 7 on the
server. I think we can go to Java 8 earlier rather than later, but I will
wait a few days to receive input from everybody in case there are issues.
