Internals of Java Virtual Machine based on challenges and experience in implementation of one of the most popular code coverage tools for Java - JaCoCo ( http://www.jacoco.org/jacoco/index.html ) that is backbone of award-winning Eclipse EclEmma Plugin ( https://www.eclipse.org/eclemma ).

In this presentation we will dive into bosom of 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?
And how it interoperates with other tools that modify bytecode, such as Mockito, PowerMock, AspectJ?
