Why does CharSequence not have String getChars(int srcBegin, int srcEnd, char[] dst, int dstBegin)

[Martin Buchholz]

Paulo,

I think you're right, that bulk char reading operations should have
been part of this interface.  But it's too late now; interfaces
can never be changed.  Hotspot does not do such a bad job
optimizing calls through interfaces.  Do we know what the
penalty is?  (usual micro-benchmark warnings apply)
