Class.__subclasses__ incompatible with Rails
--------------------------------------------
Key: JRUBY-5377
URL: http://jira.codehaus.org/browse/JRUBY-5377
Project: JRuby
Issue Type: Bug
Affects Versions: JRuby 1.6RC1
Reporter: John Firebaugh
Assignee: Thomas E Enebo
Rails's [implementation of
Class.subclasses|https://github.com/rails/rails/blob/master/activesupport/lib/active_support/core_ext/class/subclasses.rb#L6]
uses Class.\_\_subclasses\_\_ if available. 1.6.0 implements
Class.\_\_subclasses\_\_ in a way that's not compatible with what Rails
expects. I'm not sure if \_\_subclasses\_\_ is considered private in JRuby or
what, but either JRuby or Rails will need to be patched.
{code}
class A
end
module M
end
class B < A
include M
end
A.__subclasses__ #=> [M]
{code}
The expected result is [B].
