A modern programming language that makes developers happier.

kotlinlang

not sure if bug or I'm missing something I am getting warnings on this code
```result.andExpect(status().isOk)
    .andReturn()
    .response!! // Problematic line
    .contentAsClass&lt;SomeType&gt;()

inline fun &lt;reified T&gt; MockHttpServletResponse.contentAsClass(): T? =
    TestUtil.convertJsonBytesToObject(this.contentAsString, T::class.java) // This returns T```
with `!!`
```Unnecessary non-null assertion (!!) on a non-null receiver of type MockHttpServletResponse!```
without `!!`
```Call of inline function with nullable extension receiver can provoke NPE in Kotlin 1.2+ ```

method `org.springframework.test.web.servlet.MvcResult.getResponse()` has this docs/signature
```/**
 * Return the resulting response.
 * @return the response, never {@code null}
 */
MockHttpServletResponse getResponse();```
I'm using current Kotlin &amp; plugin - 1.3.71

any ideas or should I open issue?

Or maybe change the extension function to work on `MockHttpServletResponse?`

This is definitely a bug, for now you can suppress the warning "Call of inline function" with `@Suppress("PlatformExtensionReceiverOfInline")`. I will investigate this further.
