"jruby bin\rsense server" causes exception

[tohosaku]

OS: Windows 7 64bit
Ruby: jruby 1.6.0
Rsense: 0.3

When I start rsense server with jruby and command

jruby bin/rsense help

I get an error below

Exception: not opened for reading
org/jruby/RubyIO.java:1339:in `write'
bin\rsense:150:in `server_process'
bin\rsense:136:in `server_process'

bin\rsense:290:in `process'
bin\rsense:299:in `(root)'

So. I comment out line 148 of "bin\rsense"

 #sock.close_read

it woks fine for me.
