Back Button not working with Spring Boot devtools

[MarcGiffing]

If you click the back button the data are still the same and did not change as expected. I think we have to add more dependencies to the classpath releoading of spring boot devtools.

From the Spring Boot documentation:

20.2.6 Known limitations

Restart functionality does not work well with objects that are deserialized using a standard ObjectInputStream. If you need to deserialize data, you may need to use Spring’s ConfigurableObjectInputStream in combination with Thread.currentThread().getContextClassLoader().

Unfortunately, several third-party libraries deserialize without considering the context classloader. If you find such a problem, you will need to request a fix with the original authors.

Maybe a special serializer is needed when using spring boot devtools...
