Strange PATH issue on Vista if JAVA_HOME is not set
---------------------------------------------------

                 Key: JRUBY-3814
                 URL: http://jira.codehaus.org/browse/JRUBY-3814
             Project: JRuby
          Issue Type: Bug
          Components: Interpreter
    Affects Versions: JRuby 1.3.1
         Environment: Windows Vista Home Premium, JRE 1.6, JRuby 1.3.1
            Reporter: Daniel Berger


It seems that if java is not found in a user's PATH, and the JAVA_HOME 
environment variable is not set, JRuby gets confused by "(x86)" in the path.

Here was my original PATH:

Path=C:\OpenSSL\bin;C:\Python26\;C:\Perl\site\bin;C:\Perl\bin;C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Program
 Files (x86)\CyberLink\Power2Go\;c:\Program Files (x86)\Microsoft SQL 
Server\90\Tools\binn\;C:\Program Files (x86)\Git\cmd;C:\Program Files 
(x86)\GnuWin32\bin;C:\Program Files 
(x86)\QuickTime\QTSystem\;C:\OpenSSL\bin;C:\Python26\;C:\Perl\site\bin;C:\Perl\bin;C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Program
 Files (x86)\CyberLink\Power2Go\;c:\Program Files (x86)\Microsoft SQL 
Server\90\Tools\binn\;C:\Program Files (x86)\Git\cmd;C:\Program Files 
(x86)\GnuWin32\bin;C:\Program Files 
(x86)\QuickTime\QTSystem\;C:\Ruby\bin;C:\usr\local\wbin;C:\Program Files 
(x86)\PostgreSQL\8.3\bin;c:\jruby\bin

Note that putting JRuby first in the PATH did not matter.

When I tried to run "jruby -v" I got "\CyberLink\Power2Go\ was unexpected at 
this time"

The issue went away once I set my JAVA_HOME environment variable.
