# Warbler

Changes:

## 0.9.2

* Update bundled JRuby to version 1.0.3 and Goldspike 1.4.
* Add config.java_classes to allow you to copy loose Java classes into WEB-INF/classes.
* Make jar command a single command string so that jar creation doesn't fail (works around bug in JRuby 1.0.2)
* Use File.join to form staging directory, should produce the proper jar-command path in Windows
