A DESCRIPTION OF THE REQUEST :
Many Java libraries do not provide a CharSequence option in place of String arguments. I have byte arrays of ASCII text and I must first convert them to a String before passing them to such libraries. String(byte[] ascii, int hibyte)  and String(byte[] ascii, int hibyte, int offset, int count) provide the most efficient way to turn ASCII text into a string. It is unsettling that you have signalled that these constructors may be deleted in a future version of Java.

JUSTIFICATION :
The String(char[] value) constructors are an inefficient substitute because they must make _another_ copy of the char array to protect against mutation of the supplied char array. Only the deprecated constructors avoid the generation of an intermediate char array.

Note that the String constructors that take a charset String name are unacceptably inefficient because (a) the charset String name must first be parsed to determine the encoding and (b) the generic decoding process is unnecessary overhead.


CUSTOMER SUBMITTED WORKAROUND :
The workaround for avoiding the deprecated constructors is to first create a char array of ASCII text. This doubles the amount of copying and memory consumption.
