Jruby 1.7 and 9.0 fail

No changes made in the config, but it’s a couple of weeks that the jruby 1.7 and 9.0 builds fail with an installation error.

Example of failed build here

Your build has been stopped.

Probably a side effect of the default changing from Trusty to Xenial.

It’s not entirely clear to me how you would make this work on Xenial, but you could try choosing different versions of JDK, and/or pinning to older versions of JRuby.

I couldn’t find when that change happened. If it happened about a week or two ago, it could be, if the change was done before that there would be no direct link.
