When an interface without a method extends Serializable by default, everything works fine. But if the default method is used for this interface, we have a warning saying:
MyInterface.java: the serializable class MyInterface does not have a definition of serialVersionUID
He gained interest when I change this interface to an abstract class. The error will disappear.
To summarize the table, do the following:
|----------------------------|------------------|
| Type | WARNING |
|----------------------------|------------------|
| interface with no defaults | NO |
|----------------------------|------------------|
| interface with defaults | YES |
|----------------------------|------------------|
| abstract class | NO |
|----------------------------|------------------|
Is there a reason for this or is it just a mistake?
