ENV[PATH] variable not properbly set on windows
-----------------------------------------------
Key: JRUBY-3598
URL: http://jira.codehaus.org/browse/JRUBY-3598
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules, Java Integration, Windows
Affects Versions: JRuby 1.2
Environment: Windows XP SP3 ( German )
Reporter: Heusinger Jakob
When trying to use "jruby -S warble war" i get the following error:
[exec] private method `split' called for nil:NilClass
[exec]
Q:/app/codehaus/jruby_1_2_0/lib/ruby/gems/1.8/gems/rake-0.8.4/lib/rake/repaired_system.rb:109:in
`find_runnable'
[exec] (See full trace by running task with --trace)
According source line: "[nil, ".", *ENV["PATH"].split(";")].each { |path| ..."
After some research i found out whats the problem:
JRuby cant access ENV[PATH] ( its nil ), the problem is that Windows names the
Variable as "Path" instead of "PATH"
I found out that "original" ruby ignore cases when accsessing the "ENV[PATH]"
variable

When using jruby instead with the same commands i get the following output:

A fix would be to just ignore case when accessing path as done in "original"
