[Bug classpath/29619] New: Non-conformant String.replaceAll (String String)

[mwfong at csl dot sri dot com]

GNU classpath's String.replaceAll (String, String) implementation
produces different results from Sun's.

Simple Test
------ ----
public class gijReplaceAll {

    public static void main(String[] args) {
        String testString = "what-we-have here";
        String replString = testString.replaceAll ("(([^a-zA-z0-9% >:]))",
                                                   "\\\\$1");

        System.err.println ("\"" + testString + "\" " +
                            replString.length() + ": \"" + replString + "\"");
    }

}

Sun JRE 1.4.2 (Correct)
