Issue description
Using JPPF serialization (org.jppf.serialization.DefaultJPPFSerialization) to serialize/deserialize instances of classes in java.time.* packages results in exceptions like the following: 
java.io.IOException
  at org.jppf.serialization.JPPFObjectInputStream.readObjectOverride(JPPFObjectInputStream.java:96)
  at java.io.ObjectInputStream.readObject(ObjectInputStream.java:425)

  at test.time.DateTimeSerialization.copyObject(DateTimeSerialization.java:81)
  at test.time.DateTimeSerialization.main(DateTimeSerialization.java:55)

Steps to reproduce this issue
try to serialize a LocalDateTime object with JPPF serialization: 
LocalDateTime localDateTime = LocalDateTime.now();
JPPFSerialization ser = new DefaultJPPFSerialization();
try (final ByteArrayOutputStream os = new ByteArrayOutputStream()) {
  ser.serialize(object, os);
}
