There is a path through statements in the class I18nFactorySet which
discards FileNotFoundExceptions:
0. the constructor calls initFactory(servletContext, properties), which
calls initFactory(servletContext, filename); when this call is made,
defaultFactory=null;
1. initFactory(servletContext, filename) therefore calls createDefaultFactory();
2. createDefaultFactory() creates rootXmlConfig; but because
rootXmlConfig is null, a FileNotFoundException is thrown;
3. initFactory(servletContext, filename) does not catch
createDefaultFactory()'s FileNotFoundException and handle it; instead,
initFactory(servletContext, filename) throws the FileNotFoundException;
4. initFactory(servletContext, properties) catches the
FileNotFoundException but does nothing with it!
Suggestion: print the filename string when the FileNotFoundException is
caught.
My problem: I was using a config file named tiles-definitions.xml
(instead of tileDefinitions.xml, componentDefinitions.xml or
instanceDefinitions.xml).
