kotlinlang

Hi all - got a question.  In Java, I can have a Spring controller method that looks like this:
```
    @RequestMapping(value = "/something/somewhere", method = GET)
    @ResponseBody
    public String doStuff() {
        return "";
    }
```
Translating this to Kotlin, I get this:
```
    @RequestMapping(value = "/something/somewhere", method = GET)
    @ResponseBody
    fun doStuff(): String {
        return ""
    }
```
That gives me this compile error: `Type mismatch: inferred type is RequestMethod but Array&lt;RequestMethod&gt; was expected`.  
Of course, I can fix that by wrapping the RequestMethod with `arrayOf()`, like this:
```
    @RequestMapping(value = "/something/somewhere", method = arrayOf(GET))
    @ResponseBody
    fun doStuff(): String {
        return ""
    }
```
That works, but I’d like to understand — why do you have to specify the `method` as an array in Kotlin but not in Java?
