Thread-safe MessageResources[Factory]

[Scott Van Wart <sc...@indosoft.com>]

I'm implementing my own MessageResources and 
MessageResourcesFactory-derived classes.  Do these need to be 
thread-safe, specifically, the 'String MessageResources.getMessage( 
Locale locale, String key )'?

Thanks,
  Scott

The factory probably doesn't; I would expect it to be called once during 
startup. But getMessage() would need to be thread-safe unless your 
MessageResources implementation is immutable. Remember that the resource 
bundle is shared across all requests, so it will be accessed concurrently.
