Fallback applyOn with Kotlin

[Claxtastic]

When I use the applyOn parameter for @fallback in Kotlin:
@Fallback(fallbackMethod = "fallbackSaveCallEventBatch", applyOn = { SQLException::class })

I get two errors:
Annotation argument must be compile-time constant.
Type mismatch: inferred type is () -> KClass<SQLException> but Array<KClass<out Throwable!>> was expected.

Is there a correct way to do this in Kotlin, or would something have to be fixed?

The error makes it look like it's complaining that it's getting a lambda when it's expecting an array. I'm not too familiar with Kotlin, but this doc section Arrays as annotation parameters suggests that the syntax should be:

Kotlin 1.2+

@Fallback(fallbackMethod = "fallbackSaveCallEventBatch", applyOn = [ SQLException::class ])

Older versions

@Fallback(fallbackMethod = "fallbackSaveCallEventBatch", applyOn = arrayOf(SQLException::class))

Oh perfect, that works. Thanks for clearing that up.
