java.lang.reflect.InvocationTargetException is incorrectly deserialized

Name: avC70361 Date: 05/14/98



  The java.lang.reflect.InvocationTargetException is incorrectly deserialized in
jdk1.2-beta4 when have been serialized in jdk1.1.6. The exception
InvalidClassException is thrown

Here is the test demonstarating the bug.
--------------InvocationTargetExceptionTest.java--------
import java.io.*;
import java.lang.reflect.InvocationTargetException;

public class InvocationTargetExceptionTest {

  public static void main(String args[]) {

    InvocationTargetException exception = new InvocationTargetException(
      new Exception("")
    );

    if (args[0].equals("write")) {

      ObjectOutputStream stream = null;

      try {

        stream = new ObjectOutputStream(new FileOutputStream(args[1]));
        stream.writeObject(exception);
        stream.close();

      } catch(IOException e) {
        System.out.println("Couldn't write to " + args[1] + " : " + e);
        System.exit(1);
      }

      System.out.println(args[1] + " written successfully");

    } else if (args[0].equals("read")) {

      ObjectInputStream stream = null;

      try {

        stream = new ObjectInputStream(new FileInputStream(args[1]));
        exception = (InvocationTargetException)stream.readObject();

      } catch(InvalidClassException e) {
        System.out.println("Failed:" + e);
        System.exit(1);
      } catch(Exception e) {
        System.out.println(
          "Failed: couldn't read from" + args[1] + " : " + e
        );
        System.exit(1);
      }

      System.out.println("Passed");

    }

    System.exit(0);

  }

}
