Support for Shenandoah builds

[2m]

Would jabba be a good place to add support for JVM builds with Shenandoah?

Binary builds are provided by the build farm. The build numbers change daily, and only seven of the last ones are available to download. I would imagine the auto-discovery for index.json will have to be changed to support this.

I am willing to help out if you think this is a good idea.

P.S. I am a maintainer of JDK8 Shenandoah build for ArchLinux. Always changing build numbers make it tedious keeping the PKGBUILD definition up to date. I think having support for jabba would be a better approach.

Hi Martynas.

Sure, openjdk-shenandoah@1.{8,9,10}.* added (synced every 24h).

You'll need jabba@0.10.0+ for installation to work (tar.xz is not supported by jabba pre 0.10.0).

$ jabba install openjdk-shenandoah@1.10.0-235
$ java --version

openjdk 10.0.1-internal 2018-04-17
OpenJDK Runtime Environment (build 10.0.1-internal+0-nightly-sobornost-builds.shipilev.net-shenandoah-jdk10-b235)
OpenJDK 64-Bit Server VM (build 10.0.1-internal+0-nightly-sobornost-builds.shipilev.net-shenandoah-jdk10-b235, mixed mode)
