Environment

jruby 1.7.24 (1.9.3p551) 2016-01-20 bd68d85 on Java HotSpot(TM) 64-Bit Server VM 1.7.0_79-b15 +jit [Windows 7-amd64]

Expected Behavior

Since JRuby 1.7.24 is supposed to implement the language of Ruby 1.9.3, the expression [[1]].flatten(1) should evaluate to [1] (see the documentation of flatten).

Actual Behavior

ArgumentError: wrong number of arguments calling flatten (1 for 0)

The issue can be closed! I found that a Gem was the culprit: It replaced Array#flatten by its own version, which did not allow passing a parameter.
