Common test suite, broken?

[zdennis]

If I check out master and run bundle && bundle exec rake test the test suite passes.

However, if I run bundle exec rake update_common_tests && bundle exec rake test then the entire common test suite appears to fail.

Did something change upstream or on json-schema.org which is causing massive failure? This was not the case a few weeks ago and it appears that builds passed on travis about 5 days ago.

This can also be seen on this PR build: https://travis-ci.org/ruby-json-schema/json-schema/jobs/520393436
