Some of chromium's bots need java8 for their builds. The java sdk is expected to be installed on the machines prior to build run-time (ie: via puppet). It would be nice if we could expose the java version as dimension and then target that dimension specifically for any swarmbucket builds that have a dependency on it.

Note that CIPD would be a better solution for deployment of the sdk, but no one's working on that or has cycles for it given that the puppet mechanism *works well enough*
