Description
$ ruby -ve 'p [1,2].repeated_permutation(3).to_a'
ruby 1.9.2p290 (2011-07-09 revision 32553) [i686-linux]
[[1, 1, 1], [1, 1, 2], [1, 2, 1], [1, 2, 2], [2, 1, 1], [2, 1, 2], [2, 2, 1], [2, 2, 2]]
$ jruby --1.9 -e 'p [1,2].repeated_permutation(3).to_a'
[]
A patch is attached.
FYI, I found this bug by executing CRuby's test/ruby/test_array.rb 
In fact, it DOES run, though it emits many errors/failures because of
JRuby's lack of support for $SAFE, full continuation, auto-synchronized
array, etc.

The rubyspec test suite fails on this as well: rubyspec/core/array/repeated_permutation_spec.rb
ruby-doc includes this as one of the examples for repeated_permutation.
