Re: How can I trigger a @Serial warning?

Hello, Cay!

By the way, in IntelliJ IDEA we have the inspection that warns you about
wrong use of Serial:

It also suggests adding this annotation where it's appropriate:

Both inspections are turned on by default.

With best regards,

Hi Cay,

The enhancements to javac's serial lint checking have not been 
implemented as of yet. For now, @Serial is just documentation.

I tried:


@Serial private void readObject(java.io.ObjectInputStream stream, int 
shouldNotHaveThisParam) throws IOException, ClassNotFoundException

@Serial private static final String serialVersionUID = "Fred";
@Serial public String getName() { ... }

Is there some flag that I need to use? I tried -Xlint:serial, but it 
didn't make a difference.


Thanks,

How can I trigger a @Serial warning?

[Cay Horstmann]

I am trying to give an example of the utility of the @Serial annotation. 
But the JDK 17 javac doesn't seem to do anything with it. I tried:


@Serial private void readObject(java.io.ObjectInputStream stream, int 
shouldNotHaveThisParam) throws IOException, ClassNotFoundException

@Serial private static final String serialVersionUID = "Fred";
@Serial public String getName() { ... }

Is there some flag that I need to use? I tried -Xlint:serial, but it 
didn't make a difference.


Thanks,

Cay
