	    buffer.setShared();

Knowing the basic semantics of StringBuffer expansion ... this code appears
to me to allow the immutable String object to wrap a char[] that may be
larger than the string itself. And in fact ... I would bet that in the
average case where StringBuffers are being used ... the programmer is
relying on the basic semantics provided by StringBuffer for expansion ...
which I would bet means that the char[] is quite often larger than the
string itself.

Further, I wonder what happens when you then intern() a String whose char[]
is "oversized".

I *think* I understand the intent ... but I suspect that in practice ...
this turns out to be optimal less often than when it isn't ...

thoughts ?
