This reveals the problem: according to the Java documentation of
the ResourceBundle class, the above call should be written as

ResourceBundle.getBundle("resources.jtalk_deutsch");

to access the properties file (note the "." instead of the "/").
The JavaDoc states that your call is also supported, but rather
for compatibility reasons.

So there is an inconsistency between Sun's ResourceBundle and GCJ's
one. Good to know. Perhaps I should stick with good old Sun's Java.
(Apart from compatibility issues, my current app is about 400% faster
with Sun's JRE than with GCJ...)

ResourceBundle documentation:
http://java.sun.com/j2se/1.5.0/docs/api/java/util/ResourceBundle.html#getBundle(java.lang.String,%20java.util.Locale,%20java.lang.ClassLoader)

I have to admit that I am a newbie to GCJ so you will likely get
better help when you send your questions to the experts on the GCJ
mailing list (java@gcc.gnu.org).

Usually I prefer German, but as our contact evolved from GCJ's mailing
list, we make sure that the others can read our ideas as well by using
English.

Cheers,
Jens
