Code Coverage Mechanics on JVM

Java Language

Internals of Java Virtual Machine based on challenges and experience in implementation of one of the most popular code coverage tools for Java and Kotlin - JaCoCo ( http://www.jacoco.org/ ) that is backbone of award-winning Eclipse EclEmma Plugin ( https://www.eclipse.org/eclemma ). In this presentation we will dive into JVM (bytecode, restrictions, classloaders) answering on following questions: - How by developing JaCoCo we find bugs in OpenJDK? You also can! - How JaCoCo manages to work in OSGi environment? - What makes it fastest? - And which changes were required to support Java 8, 9 ... 14? Kotlin?

Scheduled on Friday from 15:10 to 16:00 in Room 5
