Examples of org.jruby.RubyModule$Autoload

org.jruby.RubyModule
Objects for holding autoload state for the defined constant. 'Module#autoload' creates this object and stores it in autoloadMap. This object can be shared with multiple threads so take care to change volatile and synchronized definitions.
