Hi! I'm still seeing this issue in the 9000 release:


C:\Users\abc\Desktop\jrubydemo>java -jar .\jruby-complete-9.0.0.0.jar --version

well, not sure it says there is no write permissions into the classloader. the problem is that default GEM_HOME is inside the jruby-complete.jar so bundler can NOT install gems there.

if the whole thing does create some strange file like "uri:classloader:/" in your current directory then this bug is not fixed.

but to use bundler or even the gem command with jruby-complete.jar you need to set GEM_HOME to install gems.
