Dynamic MessageResources ???

[Dakota Jack <da...@gmail.com>]

What is the reason why ModuleConfigImpl freezes mrconfig?  Would there
be some difficulty in making message resources dynamic?

Same reason as for freezing all the other config objects ... so that,
at runtime, you can do get() operations on the HashMaps inside with no
synchronization locking overhead.  By themselves, HashMaps are not
threadsafe, so if you allow dynamic modifications, you'll need to do
locks around every single read (which happen a lot).
