Jarified app breaks with uri:classloader:BY\ on Windows with 9.1.10.0

[stergiom]

Expected Behavior

A working Jar

Actual Behavior

The app breaks (seemingly only on Windows) at the first line require "jrubyfx" with what seems to be an error related to the :BY\ in its path..

>java -jar main.jar
Errno::ENOENT: No such file or directory - uri:classloader:BY\jrubyfx.rb
          realpath at org/jruby/RubyFile.java:864
  require_relative at uri:classloader:/jruby/kernel/kernel.rb:11
            <main> at uri:classloader:/jrubyfx.rb:34
           require at org/jruby/RubyKernel.java:961
            (root) at uri:classloader:/META-INF/jruby.home/lib/ruby/stdlib/rubygems/core_ext/kernel_require.rb:1
            <main> at classpath:/jar-bootstrap.rb:1

Can you provide an example build for us to reproduce this?

-> Example build

uri:classloader:BY\ has come up with #4612, this seems specific to expandPathInternal, it might be related to the last two letters of this statement..

looks like on windows "/THIS_IS_A_FAKE_PATH_FOR_JRUBY" is not treated as absolute path and handled differently somewhere else. a c:\THIS_IS_A_FAKE_PATH_FOR_JRUBY might work for windows platforms. @stergiom fancy to patch and try it out ?
