Is it an anti-pattern to put labels and such in property files (releated to JSP's and web development)

I see a lot of J2EE developers put labels in property files but don't use different Locales. So, you get a lot of missing property exceptions.

Java: Is clone() really ever used? What about defensive copying in getters/setters?

Do people practically ever use defensive getters/setters? To me, 99% of the time you intend for the object you set in another object to be a copy of the same object reference, and you intend for changes you make to it to also be made in the object it was set in. If you setDate(Date dt) and modify dt later, who cares? Unless I want some b...
