TornadoFX runAsyncWithProgress with nullable return type

Question

In TornadoFX the runAsyncWithProgress function is currently (as of version 1.7.19) defined as:

fun <T : Any> Node.runAsyncWithProgress(progress: Node, op: () -> T): Task<T>

The Any bound on T prohibits me from using nullable types like String? . This is very inconvenient when the operation can have a 'null result' (by being cancelled for example).

I noticed that runAsync does support nullable values, is there a reason for this difference or is it some kind of oversight? I couldn't find anything in the source code that would cause issues with possibly-null values.

事实证明，这确实是一个疏忽，现在已得到修复。
