String(byte[], String enc) misses NPE for enc == null

Name: skR10005 Date: 08/13/2001


The following JCK-tests
api/java_lang/String/i18n.html#i18nCtor[String1206]
api/java_lang/String/i18n.html#i18nCtor[String1224]
fail on jdk1.4beta-b75.

To reproduce the failure the following simple example can be used:
=================================================================
public class A {
    public static void main(String[] argv) {
        byte[] bytes = {(byte)'b'};
        try {
            new String(bytes, (String)null);
            System.out.println("No exception");
        } catch (Exception e) {
            System.out.println(e);
        }
    }
}

=================================================================
$java -version
java version "1.4.0-beta_refresh"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-beta_refresh-b75)
Java HotSpot(TM) Client VM (build 1.4.0-beta_refresh-b75, mixed mode)
$java -cp . A
No exception

At the same time:
$java -version
java version "1.4.0-beta_refresh"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-beta_refresh-b74)
Java HotSpot(TM) Client VM (build 1.4.0-beta_refresh-b74, mixed mode)
$java -cp . A
java.lang.NullPointerException

Despite the API specification for String(byte[], String enc) constructor
does not say anything about throwing NPE, this bug should be fixed because
this is a regression. All older jdk versions threw NPE.
