## [Java 4..12, Kotlin, Code Coverage and their best friend — bytecode: scandals, intrigues, investigations](https://fosdem.org/2019/schedule/event/kotlin_code_coverage_bytecode/) --- Evgeny Mandrikov
A talk I really enjoyed that I selected largely at random. Evgeny Mandrikov,
works on [JaCoCo](https://www.jacoco.org/jacoco/). They build code coverage
information by looking inside Java class files which allows them to work with
multiple JVM languages. Unfortunately, it turns out that `javac` outputs code
that... isn't quite what you'd expect. It can also be extremely different for
the same code depending on the target JVM version. The talk had a series of
interesting examples of compiler output bytecode demonstrating these issues and
proving that when you're reverse engineering, sometimes you just have to make a
guess.
