In 9.0.3.0, the global variable $INPUT_LINE_NUMBER isn't being updated correctly. Given the following program:

require 'csv'
File.open('foo.csv', 'w') do |f|
  f.write "a,b,c\n1,2,3\n4,5,6\n7,8,9\n"
end
CSV.foreach('foo.csv', headers: true) do |row|
  puts "i=#{$INPUT_LINE_NUMBER}"
end

MRI and JRuby 1.7 display:

i=2
i=3
i=4

While JRuby 9.0.3.0 displays:

i=2
i=2
i=2

now, works in 9.1.7.0 (fixed somewhere along the way) :

jruby-9.1.7.0 :001 > require 'csv'
 => true 
jruby-9.1.7.0 :002 > File.open('foo.csv', 'w') do |f|
jruby-9.1.7.0 :003 >       f.write "a,b,c\n1,2,3\n4,5,6\n7,8,9\n"
jruby-9.1.7.0 :004?>   end
 => 24 
jruby-9.1.7.0 :005 > CSV.foreach('foo.csv', headers: true) do |row|
jruby-9.1.7.0 :006 >       puts "i=#{$INPUT_LINE_NUMBER}"
jruby-9.1.7.0 :007?>   end
i=2
i=3
i=4
