StringCharBuffer and bulk get

[Chen Liang]

I think Brett is right. The spec of CharBuffer says:

The methods defined by {@code CharSequence} operate relative to the current
position of the buffer when they are invoked.

Yet getChars is an absolute bulk get method.

Since JDK25 is still in RDP, we still have a chance to fix this up.

Some methods are absolute and some relative:

CharBuffer implementation of public default void getChars(int
srcBegin, int srcEnd, char[] dst, int dstBegin) uses absolute
positioning for the indexes (i.e. ignores the current position).
