  The java.beans.beancontext.BeanContextMembershipEvent fails to be serialized
despite of implementing java.io.Serializable interface. While writing an
instance of the class java.io.NotSerializableException for class
java.util.Arrays$ArrayList is thrown.
  Here is the test demonstrating the bug.
---------BeanContextMembershipEventTest.java------
import java.beans.beancontext.*;
import java.io.*;

public class BeanContextMembershipEventTest {

  public static void main(String args[]) {
    BeanContextMembershipEvent event = null;

    ObjectOutputStream ostream = null;
    ByteArrayOutputStream baos = null;
    ObjectInputStream istream = null;

    try {

      event = new BeanContextMembershipEvent(new BeanContextSupport(), new Object[] {"string"});

      ostream = new ObjectOutputStream(
        baos = new ByteArrayOutputStream()
      );

      ostream.writeObject(event);
      ostream.flush();

    } catch(Exception e) {
      System.out.println("Unexpected exception while writing object : " + e);
      System.exit(1);
    }

    System.out.println("OK");

  }

}
------The test output-------
> java BeanContextMembershipEventTest
Unexpected exception while writing object : java.io.NotSerializableException: java.util.Arrays$ArrayList
