Description

The following code works in MRI Ruby 1.8.7 and Ruby 1.9.2:

File.open('some.file', 'r')

{|f| puts f.readbyte }

But fails with JRuby with the following error:

NoMethodError: undefined method `readbyte' for #<File:filename (closed)>

This method is similar to the getbyte() method (which does work in JRuby), but it has different behavior at EOF. See http://www.ruby-doc.org/core/classes/IO.html#M000925

It looks like the method has been added for ruby 1.9, but it should be added for 1.8.7 too.
