We decided to upgrade our application from jRuby version (1.6.7.2) to the latest release version of jRuby (1.7.10) .

Installing the application if the path contains space %20

eq: C:\Program Files

And all of a sudden our whole application was totally broken after we upgraded it to jRuby (1.7.10) if the application was installed on the path that contains space (%20).

And we never encountered any issues like this when we are using the old version of jRuby (1.6.7.2).

Windows:
org.jruby.rack.RackInitializationException: unable to resolve type 'size_t' from jar:file:/C:/Program%20Files/app/Rails_app/webroot/WEB-INF/lib/jruby-stdlib-complete-1.7.10.jar!/META-INF/jruby.home/lib/ruby/shared/ffi/types.rb:55:in `find_type' from jar:file:/

However, if I installed the application without space (%20) it is running smoothly.
