I've a model named `Role`. A `role` has a list of `Permission`s, simple as that.

Using org.springframework.boot:2.2.5.RELEASE, spring-jdbc version 5.2.24, mysql-connector-java-8.0.19, mysql server version 5.7.28

You can also checkout <https://github.com/tirbison/spring-data-jdbc-kotlin/tree/bug/mysql-list-of-enum> to reproduce the bug, do not forget to change the mysql credentials.

Role.kt

```
package com.example.demo.domain.model

import org.springframework.data.annotation.Id

class Role(
        val name: String,
        val permissions: List<Permission> = emptyList()
) {
    @Id
    var id: Long? = null
}

enum class Permission {
    READ, WRITE, EXECUTE
}

```

schema

```
create table role
(
    id          serial primary key,
    name        varchar(256),
    permissions varchar(256)
);

```

I don't have a separate table for permissions simple because **I couldn't find a way to save an `enum` collection to a table using spring-data-jdbc**, it could be a separate table or a column not so important.

When I use `H2` in-memory db I do not get any exceptions, `H2` saves enums to a column in a comma separated form. However when I use MySql I get the following exception stack trace:

```
