SPI: usage of java.util.Properties in interfaces

[Julian Reschke]

Hi,

here's a short question: is there a particular reason, why, for 
instance, RepositoryService.getRepositoryDescriptors() uses a result 
type of "Properties"?

In theory, a Map should be sufficient, and would have the benefit of 
better support in the Collections framework (such as 
Collections.unmodifiableMap()).

Best regards, Julian
