  The java.text.RuleBasedCollator fails to be serialized despite of
implementing the java.io.Serializable interface. Unexpected exception
NotSerializableException for class java.text.CompactIntArray is thrown during
the serialization process.

Here is the test demonstrating the bug:
---------------RuleBasedCollatorTest.java--------------
import java.text.RuleBasedCollator;
import java.io.IOException;
import java.io.ByteArrayOutputStream;
import java.io.ObjectOutputStream;

public class RuleBasedCollatorTest {

  public static void main(String args[]) {

    ObjectOutputStream stream = null;

    try {

      stream = new ObjectOutputStream(
        new ByteArrayOutputStream()
      );

    } catch(IOException e) {
      System.out.println("Unexpected exception : " + e);
      System.exit(1);
    }

    try {

      stream.writeObject(new RuleBasedCollator("< a < b"));

    } catch(Exception e) {
      System.out.println("Unexpected exception : " + e);
    }

  }

}
-----------The test output------------
#>java RuleBasedCollatorTest
Unexpected exception : java.io.NotSerializableException: java.text.CompactIntArray
