Excellent find Jerome, thank you! I will commit this to trunk and 1.0.

Fixed in 4315 on trunk and 4316 on 1.0 branch.

Hmm, I think this needs to be reexamined. With the patch applied, I can no longer load jirb (haven't tried with other apps):

Exception in thread "main" java.lang.NoClassDefFoundError: org/jruby/Main

If I revert the change, it works fine. Same problem/fix for both 1.x and 1_0.

WinXp, Java 1.6

Reverted in 4335 (1_0), 4336 (trunk), pending better solution. See also JRUBY-1367.

I think there's a small typo in the proposed fix above that prevents it from working. If I replace the second double-quote with a backslash, and put the double-quote after "*.jar", it works on my machine:

for %%i in ("%JRUBY_HOME%\lib*.jar") do @call "%~dp0_jrubysetcp" %%i

Sorry, that should be:

for %%i in ("%JRUBY_HOME%\lib*.jar") do @call "%~dp0_jrubysetcp" %%i

JIRA keeps eating my backslashes - trying again:

for %%i in ("%JRUBY_HOME%\lib
*.jar") do @call "%~dp0_jrubysetcp" %%i

Fourth time's the charm:

for %%i in ("%JRUBY_HOME%\lib\*.jar") do @call "%~dp0_jrubysetcp" %%i

Yep, it was just a typo in the original fix. I've committed the updated fix on both branches.

In trunk (rev 5511) I now get

$ jruby -version
Exception in thread "main" java.lang.NoClassDefFoundError: org/jruby/Main

I'm on osx 10.5.1 and java 1.5.0_13-b05-237

Kaj: that seems like you just need a rebuild or jruby.jar is missing. Either way it is unrelated to this bug. If you can still reproduce it after a clean build and your ENV looks ok please file a bug or contact us on freenode IRC in #jruby.
