WildFly (formerly known as JBoss Application Server) is an open-source JavaEE application server developed and first released by JBoss in February, 2008. The primary goal of the project is to provide a set of tools usually required for enterprise Java applications. And since the server is used for developing enterprise applications, it is especially important to minimize the number of bugs and potential vulnerabilities in its code. Today, WildFly is being developed by the large company Red Hat, and they keep the code quality at a pretty high level. That said, our analyzer was still able to find a number of programming mistakes in the project.
