warbler Warbler's gemjar feature appears to not work with JRuby 1.7.x

Originally I had always used all 3 Warbler features - compiled, executable, and gemjar. Recently when attempting to upgrade our JRuby version to 1.7.x, we found we were always getting errors upon deploying the WAR file:

org.jruby.rack.RackInitializationException: No such file or directory - /home/production/var/tmp/Jetty_0_0_.war/webapp/WEB-INF/lib/gems.jar!/gems/activesupport-3.1.3/lib/active_support/locale/en.yml

We found that removing the gemjar feature fixed this and we were able to deploy the WAR file fine. Here is the relevant StackOverflow question: http://stackoverflow.com/questions/19989858/jruby-1-7-x-compatibility-with-warbler-gemjar

This has led me to believe that there is an incompatibility with the gemjar feature and JRuby 1.7.x... Though I am unsure if this would be a Warbler bug, or a JRuby one.

Thanks!

Note this was tested and found on versions 1.3.8 and 1.4.0.beta2 of Warbler - have not tried with the new 1.4.0 release yet, but will try that

I am running into this issue too!

I see that jruby-rack supports a custom init.rb, so I'm considering using that to unzip the gems.jar on startup... monkey patch for now.

Here's a longer stack trace of what I am seeing:

Ran into this as well, turning off gemjar and rails on tomcat in linux works. Interestingly, the same war file worked in MacOS.

Also, I believe this is more of a rail issue than a warbler issue.

Just to bump, I have the exact same issue with jruby 1.7.13, removing gemjar fixes it.

I see several issues: @kodger4 it looks like an regular file with !/ after the jar-name. you could try to see if jruby-1.7.15 works better since there was some work around the LoadService. @tedpennings the stacktrace shows a "chdir" inside a jar file. jruby-1.7.15 might work

altogether there a less problems without packing gems into a jar, so turning gemjar off is the better choice.

Warbler's gemjar feature appears to not work with JRuby 1.7.x
