inline fun <reified T> blah(block: T.() -> Unit): Something {
    request = T::class.java.newInstance()

that newInstance() is deprecated, usually when you go to the source, it says why it's deprecated and what the alternative is, but this time i'm only seeing:

/** @deprecated */
@CallerSensitive
@Deprecated(
    since = "9"
)
public T newInstance() throws InstantiationException, IllegalAccessException {
    // ...
}

What is the new non-deprecated way to create an instance of a reified type in Kotlin?

Update: More information as requested:

JDK Version: 11 (not Android, just pure JVM)
Kotlin Version:1.3.61

Actually this comes from Java itself. The appropriate replacement is:

T::class.java.getDeclaredConstructor().newInstance()

You can also check the Class.newInstance()-Javadoc which states that too.

    `getDeclaredConstructor` (note the missing `s`) should work... it accepts a variable amount of parameter types... – Roland Feb 10 '20 at 09:01
