After upgrading to Jenkins 1.518 (from 1.517) last night, the ruby-runtime plugin disappeared from the list of installed plugins. Attempting to reinstall the plugin fails, and results in a stack trace ending with:
Caused by: org.jruby.embed.EvalFailedException: java.lang.IncompatibleClassChangeError: Found class com.kenai.jffi.InvocationBuffer, but interface was expected
A little googling suggests that this is a backwards incompatibility between jruby and more recent versions jffi.

[JENKINS-18314] Possible incompatibility between jffi-1.2.7 and jruby 1.6.5 as shipped with ruby-runtime plugin

This causes dependent plugins to also fail and build configs which reference them to not load. Downgrading to 1.517 fixes.

added a comment - Close this issue since JENKINS-18311 has been fixed. Yuu Yamashita
added a comment - This problem has been fixed in ruby-runtime 0.11. 
To further support this, rolling back to 1.517 completely resolves this issue. ruby-runtime re-appears in the list of installed apps, along with any plugins that depend on it.
