Hi,

First off, happy new year to the Yasson team.
I've done another small test using a class with an Optional<java.util.Date> attribute. It seems that there is a marshalling error on it. When calling jsonb.toJson a JsonbException is thrown (see comment in my attached code).
In the spec, it is mentionned that implementations MUST support binding of standard Java date/time classes including java.util.Date (chapter 3.5).
Is it a bug or a bad usage from me?

Hi Jean-Francis

You're right. Seems it's a bug Sad . I'll take a look at it and put it in issues list.

Thanks

Just as a workaround, if you set the visibility of the inner class (i.e. Person) to public, you'll not get this error. It's not related to the Optional field. I've to investigate more to see if still this is a bug or it's something that is not going to be supported by the API.

According to the spec [3.7.1] only public and protected nested classes are supported. As I see you have package private (default) access in your sample.
