Yuri, I'm trying to test serialization but the simple test: import java.io.*; public class Test { public static void main(String[] args) throws Throwable { ObjectOutputStream oos = new ObjectOutputStream(new ByteArrayOutputStream()); oos.writeObject(new Object()); } } fails: java.lang.Error: java.security.NoSuchAlgorithmException: MessageDigest SHA imple mentation not found at java.io.ObjectStreamClass.computeSerialVersionUID(ObjectStreamClass.j ava:345) ........ I've built a version of classlib with your patch but the test still fails. Is it because I didn't apply it correctly or maybe something else is missing? -- Regards, Anton Luht, Intel Middleware Products Division --------------------------------------------------------------------- Terms of use : http://incubator.apache.org/harmony/mailing.html To unsubscribe, e-mail: harmony-dev-unsubscribe@incubator.apache.org For additional commands, e-mail: harmony-dev-help@incubator.apache.org
