javax.swing.text.Segment preserves the semantics of a shared buffer. 
It's not a drop-in replacement for String (many of the methods differ or 
are absent). But Segment is extensible, so critical missing methods 
could be added.

I wonder if the best way to go would be to cheat and have String 
extended into a SharedString with the old implementation.  This would 
violate the finality of String, but it's possible to synthesize these 
sorts of things if one has control of the JVM.  Obviously, this needs to 
come from Oracle.
