Following through the instructions given in the following link doesn't really enable the macro library (macros.vm) to reload automatically.

• http://confluence.atlassian.com/pages/viewpage.action?pageId=137633

Instructions:
Perform the following modifications before starting the server, or restart it afterwards:

1. Edit ./confluence/src/etc/java/velocity.properties (or /WEB-INF/classes/velocity.properties if you are using the webapp).
2. Set all the "...resource.loader.cache" values to false.
3. Set the "class.resource.loader.cache" to false.
4. Set "velocimacro.library.autoreload" to true (uncomment the line if necessary).

This has been tested in 2.3 as well and it didn't auto reload when I made changes to macros. vm
