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

[Gábor Boskovits]

Hello!

I just run a quick grep to see which files might be interesting.

We use ant-build-system in:

axoloti.scm *

bioinformatics.scm *

compression.scm *

icu4c.scm

java.scm *

libusb.scm *

music.scm *

textutlis.scm

uml.scm *

version-control.scm *

web.scm *

xml.scm

Only the ant-build system uses icedtea among build systems.

Icedtea is explicitly metioned in the ones maked with *, and:

kodi.scm

math.scm

ruby.scm

We have a definition in place where currently icedtea is defined to be icedtea-7.

I guess we could just flip that to icedtea-8, and check what still works.

That would flip the version in the build system also, as it uses "icedtea".

Should I check which packages are affected in advance, or just go with the build and see what does not work?

OK, I'll find some time to work on this in the coming days.  I'll send
you an update by the end of this month at the latest.
