Prototype

public static <T> T instantiateClass(Class<T> clazz) throws BeanInstantiationException

Document

Instantiate a class using its 'primary' constructor (for Kotlin classes, potentially having default arguments declared) or its default constructor (for regular Java classes, expecting a standard no-arg setup).
