NullPointerException thrown by Charset.availableCharsets (with jconn4.jar in classpath)

Hello,

The following test case:

import java.nio.charset.Charset;
import java.util.Iterator;
import java.util.Set;

public class TestCase {
    public static void main(String[] args) {        Set set = Charset.availableCharsets().keySet();        for (Iterator iterator = set.iterator(); iterator.hasNext();) {            String s = (String) iterator.next();            System.out.println(s);        }    }
}

throws a NPE when jconn4.jar is in the classpath.

See stacktrace here:

Exception in thread "main" java.lang.NullPointerException          at java.nio.charset.Charset.put(Charset.java:550)          at java.nio.charset.Charset.access$300(Charset.java:276)          at java.nio.charset.Charset$4.run(Charset.java:593)          at java.nio.charset.Charset$4.run(Charset.java:585)          at java.security.AccessController.doPrivileged(Native Method)          at java.nio.charset.Charset.availableCharsets(Charset.java:584)          at pack.TestCase.main(TestCase.java:9)

Is this a bug in the sybase ase driver? Can anyone please advise?

Regards,

J.
