-----------------------------------
I think this is a JRuby issue, I can reproduce it easily:
{noformat}
mdrob@mdrob-MBP:~/IdeaProjects/hbase$ cat test.rb
require 'irb/ruby-lex'
scanner = RubyLex.new
scanner.set_input(STDIN)
scanner.each_top_level_statement do |s, linenum|
puts s
end
mdrob@mdrob-MBP:~/IdeaProjects/hbase$ echo "foo" | ruby test.rb
NoMethodError: undefined method `encoding' for #<IO:<STDIN>>
Did you mean? set_encoding
