creating a directory via uri-like path 'uri:classloader://new_dir' acts wrongly #2972
Description
a classloader or classpath is not associated to single "path" and might not even have any path on filesystem.
just a few examples:
$ bin/jruby -rfileutils -e 'p FileUtils.mkdir "uri:classloader://new_dir"'
Errno::ENOENT: No such file or directory - /home/christian/projects/active/jruby/jruby/uri:classloader:/new_dir
mkdir at org/jruby/RubyDir.java:460
fu_mkdir at /home/christian/projects/active/jruby/jruby/lib/ruby/1.9/fileutils.rb:247
mkdir at /home/christian/projects/active/jruby/jruby/lib/ruby/1.9/fileutils.rb:176
each at org/jruby/RubyArray.java:1613
mkdir at /home/christian/projects/active/jruby/jruby/lib/ruby/1.9/fileutils.rb:175
(root) at -e:1
same with Dir
$ bin/jruby -e 'p Dir.mkdir "uri:classloader://new_dir"'
Errno::ENOENT: No such file or directory - /home/christian/projects/active/jruby/jruby/uri:classloader:/new_dir
mkdir at org/jruby/RubyDir.java:460
(root) at -e:1
and with mkdir_p things are different:
$ bin/jruby -rfileutils -e 'p FileUtils.mkdir_p "uri:classloader://new_dir"'
["uri:classloader://new_dir"]
which just creates a something on the filesystem.
using the runnable.jar from this integration test
mvn -Pmain -Dinvoker.test=runnable
behaves slightly different:
$ java -jar maven/jruby/target/it/runnable/runnable.jar -rfileutils -e 'p FileUtils.mkdir "uri:classloader://new_dir"'

some exception with Dir.mkdir or FileUtils.mkdir
all this happens even if

true
