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

This doesn't just introduce a source incompatibility (requiring code
to be recompiled), it also introduces a binary incompatibility. If any
object receives a CharSequence instance that happened to have been
compiled against an older version of the platform, it will have no way
of knowing that this method does not exist on the object.
Java hasn't (to my knowledge) ever broken compatibility with an
interface in the platform API before. I consider that a great strength
of the platform.
