Files added to a module via Kernel.autoload are not automatically loaded if the
class they contain is extended
--------------------------------------------------------------------------------------------------------------
Key: JRUBY-1345
URL: http://jira.codehaus.org/browse/JRUBY-1345
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules, Interpreter
Affects Versions: JRuby 1.0.1
Reporter: Daniel Einspanjer
Attachments: overriding_plugins.zip
Discovered while trying to run a Rails project under JRuby. The project makes
use of ActiveScaffold and a second plugin that extends ActiveScaffold.
AS uses autoload for all the files in its library.
The second plugin extends one of the classes in AS in the following way:
module Foo::Bar
class Baz
def a_method_new
end
alias_method_chain :a_method, :new
end
end
This works in MRI but in JRuby, the Foo::Bar::Baz class is not autoloaded and
the alias causes the application to crash with an "undefined method" NameError
Attached is a test case that demonstrates the problem. Expand the zip into the
vendor/plugins directory of a new rails project and attempt to start the
project via jruby script/server
