no such file to load -- json

[zimbatm]

Symptom

Error loading fact /var/lib/puppet/lib/facter/jenkins.rb no such file to load -- json

Analysis

On Ubuntu 12.04, the puppet package depends on ruby (1.8.7) and json is not installed. json only started being included in later versions of ruby.

It's possible to work around the issue by installing the ruby-json package but since the issue is occurring in the facter plugin it will only start working after at least one run. If jenkins is not installed on that host the facter plugin would still run an ruby-json never be installed.

One solution would be to bundle okjson, a pure ruby implementation of the JSON format and require it as a fallback.

@zimbatm thank you for a very well written bug report!

I'll take a look at okjson fallback, that's a good suggestion
