The docs for Range#eql? in MRI say a Range object is eql? if start1 && start2 are eql? and end1 && end2 are eql? However, it seems JRuby is treating a float as an int:

Range.new(1.0, 25).eql?(Range.new(1, 25)) # true, but should be false

Since 1.eql?(1.0) is false, the above should be false as well.
