Issue: Exposed generated duplicate columns
Transaction attempt #0 failed: org.h2.jdbc.JdbcSQLException: Duplicate column name "NAME";

Code:

object Users : IntIdTable() {
    val name = varchar("name", length = 50).uniqueIndex()
}

class User(id: EntityID<Int>) : IntEntity(id) {
    companion object : IntEntityClass<User>(Users)

    var name by Users.name
}

object Groups : IntIdTable() {
    val name = Users.varchar("name", length = 50)
}

class Group(id: EntityID<Int>) : IntEntity(id) {
    companion object : IntEntityClass<Group>(Groups)

    var name by Groups.name
}

fun main(args: Array<String>) {
    Database.connect("jdbc:h2:mem:test", driver = "org.h2.Driver")

    transaction {
        addLogger(StdOutSqlLogger)

        SchemaUtils.create(Users, Groups)
    }
}

Why you use val name = Users.varchar("name", length = 50) in Groups table definition?
This will add "name" column to Users instead of Groups.

Sorry, I used Intellij IDEA's copy function.

Yeah, this copy sometimes requires more time than it saves :D
