Two features distinguish Java from other main-stream programming
languages like C and C++: its built-in support for concurrency and
safety guarantees such as type safety or safe execution in a sandbox.
In this work, we build a formal, unified model of Java concurrency,
validate it empirically, and analyse it with respect to the safety
guarantees using a proof assistant. We show that type safety and
Java's data race freedom guarantee hold. Our analysis, however,
revealed a weakness in the Java security architecture, because the
Java memory model theoretically allows pointer forgery. As a result,
this work clarifies the specification of the Java memory model.
