Ownership types were devised nearly 15 years ago to provide a stronger notion of protection
to object-oriented programming languages. Rather than simply protecting the fields of an …

A key challenge for concurrent programming is that side-effects (memory operations) in one
thread can affect the behavior of another thread. In this paper, we present a type system to …

A program verifier is a tool that allows developers to prove that their code satisfies its
specification for every possible input and every thread schedule. These lecture notes …

This paper proposes a new type system for concurrent programs, allowing threads to
exchange complex object graphs without risking destructive data races. While this goal is …

The proliferation of shared mutable state in object-oriented programming complicates
software development as two seemingly unrelated operations may interact via an alias and …

Active objects offer a structured approach to concurrency, encapsulating both unshared
state and a thread of control. For efficient data transfer, data should be passed by reference …

Programming efficient distributed, concurrent systems requires new abstractions that go
beyond traditional sequential programming. But programmers already have trouble getting …

This paper presents a simple type system for thread-local data in Java. Classes and types
are annotated to express thread-locality and unintended leaks are detected at compile-time …

Abstract This paper presents Welterweight Java (WJ), a new minimal core Java calculus
intended to be a suitable starting point for investigations in the semantics of Java-like …

Dealing with aliasing is one of the key challenges for the verification of imperative programs.
For instance, aliases make it difficult to determine which abstractions are potentially affected …
