Ok, I've just attached the files...too complicated to find somewhere to put them..

test.class is the class "ruby.test". jruby.jar is JRuby's jar. Run with:

java -client -cp jruby.jar:. ruby.test

(assuming you put the test.class in ./ruby)

It should crash under any version of JDK 6 client compiler.

I've also attached the Ruby source. If you want to just run it directly, and JRuby will compile it before run, do it like this:

java -jar jruby.jar org.jruby.Main test.rb

$ok = true

def getc
 if $ok
   $ok = false
   nil
 else
   $ok = true
   50
 end
end

def gets
 c = getc or return
 l = ""
 begin
   l.concat c unless c == "\r"
   break if c == "\n"
 end while c = getc
 l
end

loop { gets }
