Re: java: switch to icedtea-8 as default JDK

[Gábor Boskovits]

Ok, I just made a branch, basically only changing that single line in java.scm.

It's base on current core-updates.

You can clone from: https://github.com/Boskovits/guix.git

branch: change-default-icedtea-8.

How do we know where you need further assistance with that?

As first step it is not needed to remove #:jdk icedtea-8 references, because I think that simply becomes a noop. Am I right here?

That can be done as the last step before merging, I guess.

Exactly.  The call for help is really about dealing with the fallout
from this change.  I’ve attempted this some time ago when we still had
a much smaller set of Java packages, but it’s too much to check all of
the packages by myself.

For some packages it’s feasible to do this immediately before pushing.
It’s also good to review the weird hacks that were sometimes necessary,
and check if they are still needed.

We also need to confirm that the generated build.xml files have the
appropriate “source” and “target” version specifiers.

But mostly we can just change the default “icedtea” and remove “#:jdk
,icedtea-8” from all packages.  I’d like to avoid having to add “#:jdk
,icedtea-7” to any of the packages; finding fixes would be preferrable.
