Antonio Petrelli commented on TILES-515:
----------------------------------------

Personally I would like to support OSGi containers, so I would like to fix it, 
since we already have fixed some issues that made the use of Tiles under OSGi 
impossible.
Using the message of and exception is a bad practice and very dangerous, a more 
specific IOException can be a solution. However I would like to reproduce the 
problem.
Please, provide a test case and instructions on how to deploy it in an OSGi 
container.

> The BaseLocaleUrlDefinitionDAO does not handle loading view definitions 
> directly from a war bundle properly. In the loadDefinitionsFromURL() call, it 
> catches a FileNotFoundException if a definition is not found, logs a debug 
> message and continues. This is the proper way to handle situations where a 
> view definition has not been defined for a particular locale. However, when 
> loading from a resource URL (e.g. "classpath:/..." or "bundle:/"), if the 
> view definition is not found, a "FileNotFoundException is not thrown, rather 
> an IOException is. A plain IOException is not consumed, but rather thrown, 
> and prevents Tiles from initializing.
> The code is in BaseLocaleUrlDefinitionDAO, line 277. The IOException handling 
> should check if it is a resource not found error and ignore the exception if 
> so.
