I don't know of a string handling package like that, but here's
code for two of your wish list items. I won't vouch for these being the
fastest possible, but they work.

The Beans property change event model has nothing specific to GUIs.
It works quite well for general event notification. And there's a
level more abstract than that if necessary, just code your own event
objects and event listeners. Those won't cross JVM boundaries
automatically but it's not hard to code.
