No properties file found Error for ReloadableResourceBundleMessageSource

Question

I'm trying to use a reloadable spring resource bundle but spring cannot find the file. I've tried tons of different paths, but can't get it to work anywhere. In the code below you'll see that i load both the spring bundle and the regular one from the same path variable but only one works.

I've been banging my head against this for far too long. Anybody have any ideas?

rather than reading from a file, you should probably read from the classpath using

Messages.class.getResourceAsStream("/path/from/classpathroot/messages.properties")
