It looks like various IO methods in Ruby 2.2 support numeric limits instead of, or in addition to, separators. This one is making JRuby blow up:

# MRI
IO.readlines('test.txt', 0) # => ArgumentError: invalid limit: 0 for readlines

# JRuby
IO.readlines('test.txt', 0) # => java.lang.OutOfMemoryError: Java heap space
