Java.lang.ClassNotFoundException: boolean

Question

I came accross a problem with a specific version of the sun jdk : 1.3.1_11
I didn't see anything in forums about it, or in the bug database, so I thought I would share it here :
the following program runs perfectly with 1.3.1_03 or 1.4 or JRockit JVM, but on 1.3.1_11-b02 (at least the linux version), it generates the exception that is in the subject of this post.
import java.io.ByteArrayInputStream;
import java.io.ByteArrayOutputStream;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import java.lang.reflect.Method;
public class TestSerMain {
     public static void main(String[] args) throws Exception {
          Class c = TestSerMain.class;
          Method[] m = c.getMethods();
          for (int i=0; i<m.length; i++) {
               if ("myMethod".equals(m.getName())) {
                    Class[] params = m[i].getParameterTypes();
                    displayClassArray("orignal",params);
                    ByteArrayOutputStream bos = new ByteArrayOutputStream();
                    ObjectOutputStream os = new ObjectOutputStream(bos);
                    os.writeObject(params);
                    byte[] serialized = bos.toByteArray();
                    System.out.println("serialized in "+serialized.length+" bytes.");
                    ByteArrayInputStream bis = new ByteArrayInputStream(serialized);
                    ObjectInputStream is = new ObjectInputStream(bis);
                    Class[] deserialized = (Class[]) is.readObject();
                    displayClassArray("deserialized",params);
     private static void displayClassArray(String string, Class[] params) {
          System.out.println("************");
          System.out.println(string);
          for (int i=0; i<params.length; i++) {
               System.out.println(params[i]);
     public void myMethod(String s, boolean b) {}

Answer 1

well, just found out, that it's bug # 4171142
and there's a workaround for it: overriding ObjectInputStream (!)
