This repo is a sample to reproduce the issue described here - https://stackoverflow.com/questions/51085138/kotlin-data-class-and-bean-validation-with-container-element-constraints

The test in BeanValidationContainerConstraintsApplicationTests fails because it expects two validation errors:

• name is empty
• the map value in someMap

data class SamplePayload(
    @field:NotEmpty val name: String,
    @field:NotEmpty val someMap: Map<String, @NotEmpty String>)

The @NotEmpty annotation on the value type of the map someMap is not considered.

See https://beanvalidation.org/2.0/spec/#constraintdeclarationvalidationprocess-containerelementconstraints.

Run the test with:

./gradlew test
