. Do You Really Get Class Loaders
Class loaders are at the core of the Java language. Java EE containers, OSGi, NetBeans modules, Tapestry 5, Grails, and many others use class loaders heavily. Yet if something went wrong, would you know how to solve it?

This session takes a tour of the Java class loading mechanism, from both the JVM and developer points of view.

It looks at typical class loading problems and how to solve them. ClassNoDefError, IncompatibleClassChangeError, LinkageError, and many others are symptoms of specific things going wrong that you can usually find and fix.
For each problem, the presentation goes through a hands-on demo with a corresponding solution. It also takes a look at how and why class loaders leak and how you can remedy that.
Productive and Effective Development with Spring and Java EE
This live coding session shines some light on a range of productivity tools that make software development a pleasure rather than a chore.

Simon will live-code two applications. The first, a Java EE application with JBoss Forge that uses JPA, Bean Validation, REST, and Angular, is tested with Arquillian from within JBoss Forge. You’ll see how a Java EE microservice can be developed in Forge and run with JBoss Swarm. The second application is developed on Spring Boot, and you’ll see how to develop and run a Spring application with JRebel. You’ll learn how to write code productively with tools designed for developers.
