Nicolas Fränkel: Checked exceptions and lambdas
Java’s checked exceptions were a massive improvement over C’s error-handling mechanism. As time passed and experience accumulated, we collectively concluded that we weren’t there yet. However, Java’s focus on stability has kept checked exceptions in its existing API. Java 8 brought lambdas after the 'checked exceptions are great' trend. None of the functional interface methods accepts a checked exception. In this post, I will demonstrate three different approaches to mak

Wie verändern #SnapStart & #GraalVM die Startzeiten von Java-#Lambdas? @VKazulkin liefert reproduzierbare Messdaten, zeigt Performanceeffekte verschiedener Priming-Techniken & dokumentiert die Umsetzung mit #AWS SAM & #Quarkus.
