JVM implementation details behind Java Lambdas.

With Java 7 invokedynamic was added to the JVM instruction set and the concept of method handles was introduced — but not used at all by the Java language compiler. This changed the first time when Java 8 lambda expressions and method references were introduced. More tricks are introduced with Java 9 for efficient string operations.

In this session we explore the technical details of compiled lambda expressions and learn about the new JVM capabilities — which come with several performance benefits and could also be used for other JVM languages.
