      if object constructed by anonymous inner class will be serialized in jdk version before 1.3
      then it can not be deserialized in jdk version after 1.3 - this is a compatibility problem.
      This is a test which illustrate this bug:
      --------
      public class test {

        public static void main(String[] args) {
          if (args.length == 0) {
                  java.awt.Frame m =
      new java.awt.Frame() {
      public boolean isResizable() {
                              return false;
      }
      };
              try {
                  java.io.FileOutputStream fs =
                      new java.io.FileOutputStream("test.ser");
                  java.io.ObjectOutputStream oos =
                      new java.io.ObjectOutputStream(fs);
                  oos.writeObject(m);
                  oos.close();
      } catch (java.io.IOException e) {
                  System.out.println("FAILED:" + e);
      }
          } else {
              Object m = null;
              try {
                  java.io.FileInputStream fs =
                      new java.io.FileInputStream("test.ser");
                  java.io.ObjectInputStream ois =
                      new java.io.ObjectInputStream(fs);
                  m = ois.readObject();
                  ois.close();
      } catch (java.io.IOException e) {
                  System.out.println("FAILED:" + e);
      } catch (ClassNotFoundException e) {
                  System.out.println("FAILED:" + e);
      }
              if (m instanceof java.awt.Frame) {
                  System.out.println("OKAY");
      } else {
                  System.out.println("FAILED");
      }
          }
        }

      }
      --------
      This test was compiled under jdk 1.2 and executed with no command line parameters for creating
      file test.ser.
      Corresponded commands are:
      -----
      javac - d . test.java
      java -cplasspath .:$CLASSPATH test
      -----
      Then it was compiled under jdk version 1.4 and executed with one command line parameters for
      deserializing an object from test.ser.
      Corresponded commands are:
      -----
      javac - d . test.java
      java -classpath .:$CLASSPATH test tt
      -----

      Output:
      --------
      FAILED:java.io.InvalidClassException: test$1; Local class not compatible: stream classdesc
      serialVersionUID=6045298662845868053 local class serialVersionUID=7406725469941465764
      FAILED
      --------
      Note: this bug is reproduced only if test is RECOMPILED for each jdk version.

      It needs to be fixed.

      Jusification:
      The following JCK test failure:
