Resources cannot be located when jRebel is enabled

I am currently using wro4j deployed into a Tomcat 6.0.35 container with Google 
Guice. Unfortunately, as soon as I enable JRebel, wro4j is no longer able to 
locate its resources (configured in wro4j.xml), but instead produces an 
aggregate .js file that is mostly empty (except for some boilerplate JavaScript 
[1] per resource).

In the log I get messages like these:

In the concurrently produced rebel.log I see that the class loader is actually 
attempting to locate /backbone/views/show_view.coffee instead of 
/js/backbone/views/show_view.coffee:

-- 8< --

I am setting up the WroFilter like this (in an JerseyServletModule):

-- 8< --
bind(WroFilter.class).in(Singleton.class);
filter("/js-min/*").through(WroFilter.class);
-- 8< --

wro.properties:

uriLocators=servletContext,classpath
preProcessors=coffeeScript
