Attribute type checking on field with @Converter

I've created custom type for entity field and made a @Converter for it, But Idea 13.1 claims about 'Attribute type checking'

I created a test project on github.
Is it my fault or Idea does not support this feature of JPA 2.1?

JavaDoc says: The simplest type of mapping to a database column. The

Basic

annotation can be applied to a persistent property or instance variable of any of the following types: Java primitive types, wrappers of the primitive types,

String

java.math.BigInteger

java.math.BigDecimal

java.util.Date

java.util.Calendar

java.sql.Date

java.sql.Time

java.sql.Timestamp

byte[]

Byte[]

char[]

Character[]

, enums, and any other type that implements

java.io.Serializable

.

Does your class CustomConverted implements java.io.Serializable?

No CustomConverted does not implements Serializable. But it has a @Converter assigned.

JPA 2.1 Specification, section 3.8 says: An attribute converter must implement

javax.persistence.AttributeConverter

interface. A converter implementation class must be annotated with the

Converter

annotation or defined in the XML descriptor as a converter. If the value of the

autoApply

element of the Converter annotation is

true

, the converter will be applied to all attributes of the target type, including to basic attribute values that are contained within other, more complex attribute types.
