Re: [jruby-user] Out of memory problem with JRuby-Complete

I wonder if this issue is related to 
https://github.com/jruby/jruby/issues/1888. Basically, there is a memory 
leak in JRuby 1.7.13 triggered by loading files from a jar, which 
happens quite a lot when you use jruby-complete.jar to run an application.

If you're up for building from source, the "jruby-1_7" branch in git has 
a fix for this issue.
