bean validation not working with kotlin (JSR 380)

Question

so first of all i could not think of a better title for this question so i\'m open for changes.

I am trying to validate a bean using the bean validation mechanism (JSR-3

Answer 1

Try adding ? like this:

data class User(
    @field:Valid
    @field:NotEmpty
    var roles: MutableSet<@NotNull Role?> = HashSet()
)

Then the kotlin compiler should realise roles could be null, and it might honor the validation, I know little about JSR380 so i'm just guessing though.
