JDK-6893628 - Add support for StringBuilder to java.util.regex.Matcher

JDK-6340041 - Matcher appendTail and appendReplacement should take CharSequence
Description
Name: jl125535			Date: 06/22/2004


A DESCRIPTION OF THE REQUEST :
The methods appendReplacement and appendTail in java.util.regex.Matcher would be even more effective if there were counterparts that used the Appendable interface as parameters and/or return values.

public Matcher appendReplacement(Appendable sb, String replacement)

public Appendable appendTail(Appendable sb)



JUSTIFICATION :
Since these methods are used to build strings, then I could easily use a StringBuilder or a PrintWriter as a replacement for StringBuffer, thus saving synchronization or copying overhead.
