Hash Subclass#== not respected when checking equality of collections.
---------------------------------------------------------------------
Key: JRUBY-5883
URL: https://jira.codehaus.org/browse/JRUBY-5883
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules, Ruby 1.8.7, Ruby 1.9.2
Affects Versions: JRuby 1.6.2
Environment: OSX Snow Leopard 10.6.7, Java 1.6.0_24, JRuby 1.6.2
installed through RVM 1.6.20
Reporter: Zach Moazeni
When subclassing a Hash and overriding "==()" instance1 == instance2 works, but
[instance1] == [instance2] doesn't. This behavior is inconsistent with mri
1.8.7, 1.9.2, and rubinius.
{code}
class HashSubclass < Hash
def ==(other)
self["some_key"] == other["some_key"]
end
end
h1 = HashSubclass.new
h2 = HashSubclass.new
h1["some_key"] = 1
h2["some_key"] = 1
h2["some_other_key"] = 1
h1 == h2 # true on JRuby, 1.8.7, 1.9.2, Rubinius
[h1] == [h2] # false on JRuby. True on 1.8.7, 1.9.2, Rubinius
{code}
