I'm pretty sure its not an API design to disallow this. So its 
implementation specific and your argument that Sun does not do it is 
indeed a pretty strong one.  I'm not sure I agree with it, but its a good 
argument nontheless.

I do disagree that this assumtion makes caching impossible, I even would 
go so far as to say its really wanted and what people expect due to the 
expected uptime of servers like tomcat.

My original point still stands;  loading "foo.properties" while 
"foo_nl_NL.properties" was requested will effectively make it impossible 
to find foo_nl* if its placed in the classpath later.  Which is 
definitely not what I expect.

Solution isn't that hard; you can use dnotify or even simple stats on 
fetch-from-cache to check your cache being dirty, for example.
