Documentation uses old java 8 style and for code samples and at same time uses Kotlin val style.
Here is an example
Java (now)
ApplicationContext context = new ClassPathXmlApplicationContext("services.xml", "daos.xml");
Kotlin(now)
val context = ClassPathXmlApplicationContext("services.xml", "daos.xml")
Please, use Java 11 style so java section should be:
var context = new ClassPathXmlApplicationContext("services.xml", "daos.xml");

Thanks for the suggestion but Spring Framework has support for Java 8 still and it would be misleading to have samples showcased in the doc that do not work with Java 8.
