How can I get around Overload resolution ambiguity for a function that has two varargs single-argument signatures?

Overload resolution ambiguity. All these functions match.
public open fun <T : Any!> array(vararg values: TypeVariable(T)!): Field<Array<(out) TypeVariable(T)!>!> defined in org.jooq.impl.DSL
public open fun <T : Any!> array(vararg fields: Field<TypeVariable(T)!>!): Field<Array<(out) TypeVariable(T)!>!> defined in org.jooq.impl.DSL

It works in Java, but not in Kotlin. I can't use null or `emptyArray()`/`emptyList()` because that produces the wrong results =/

[ephemient]

DSL.array(*emptyArray<T>())
DSL.array(*emptyArray<Field<T>>())

but looking at the javadoc, there's a non-varargs overload that you could use instead, if that is your intended result

DSL.array(emptyList<T>())

(but what use is an empty array in jOOQ?)

@ephemient Sorry, meant to follow up on this but it slipped my mind

Ah, I need it to coalesce potentially null aggregation results in a JSON object, for a custom SQL dialect that isn't supported by default
coalesce(some_agg_column, [])
