Safe initialization of objects

The inception of object-oriented programming introduces a category of bugs related to object construction: initialization errors. Every newly created object goes through several initialization states: starting from a state where all fields are uninitialize ...

Just-in-time performance without warm-up

Denys Shabalin

Scala has been developed as a language that deeply integrates with the Java ecosystem. It offers seamless interoperability with existing Java libraries. Since the Scala compiler targets Java bytecode, Scala programs have access to high-performance runtimes ...

Cross-Platform Language Design

Sébastien Jean R Doeraene

Programming languages are increasingly compiled to multiple runtimes, each featuring their own rich structures such as their object model. Furthermore, they need to interact with other languages targeting said runtimes. A language targeting only one runtim ...

Interflow: interprocedural flow-sensitive type inference and method duplication

Martin Odersky, Denys Shabalin

Scala heavily relies on a number of object-oriented abstractions to support its feature-rich collections library. There are known techniques that optimize those abstractions away in just-in-time (JIT) compilers, but applying them in the ahead-of-time (AOT) ...

Java and Scala's Type Systems are Unsound The Existential Crisis of Null Pointers

Nada Amin

We present short programs that demonstrate the unsoundness of Java and Scala's current type systems. In particular, these programs provide parametrically polymorphic functions that can turn any type into any type without (down) casting. Fortunately, parame ...

Synthesizing Java Expressions from Free-Form Queries

Viktor Kuncak, Tihomir Gvero

We present a new code assistance tool for integrated development environments. Our system accepts as input free-form queries containing a mixture of English and Java, and produces Java code expressions that take the query into account and respect syntax, t ...

Java and Scala's Type Systems are Unsound: The Existential Crisis of Null Pointers

We present short programs that demonstrate the unsoundness of Java and Scala’s current type systems. In particular, these programs provide parametrically polymorphic functions that can turn any type into any type without (down)casting. Fortunately, paramet ...

Architecture Internalisation in BIP

Simon Bliudze, Joseph Sifakis

We consider two approaches for building component-based systems, which we call respectively architecture-based and architecture-agnostic. The former consists in describing coordination constraints in a purely declarative manner through parameterizable glue ...

Surgical Precision JIT Compilers

Tiark Rompf, Hassan Chafi

Just-in-time (JIT) compilation of running programs provides more optimization opportunities than offline compilation. Modern JIT compilers, such as those in virtual machines like Oracle's HotSpot for Java or Google's V8 for JavaScript, rely on dynamic prof ...

Cell Guidance on Nanogratings: A Computational Model of the Interplay between PC12 Growth Cones and Nanostructures

Silvestro Micera

Background: Recently, the effects of nanogratings have been investigated on PC12 with respect to cell polarity, neuronal differentiation, migration, maturation of focal adhesions and alignment of neurites. Methodology/Principal Findings: A synergistic proc ...

Miniboxing: Improving the Speed to Code Size Tradeoff in Parametric Polymorphism Translations

Martin Odersky, Vlad Ureche, Cristian Talau

Parametric polymorphism enables code reuse and type safety. Underneath the uniform interface exposed to programmers, however, its low level implementation has to cope with inherently non-uniform data: value types of different sizes and semantics (bytes, in ...

Composing Relaxed Transactions

Rachid Guerraoui, Vincent Gramoli, Mihai Letia

As the classic transactional abstraction is sometimes considered too restrictive in leveraging parallelism, a lot of work has been devoted to devising relaxed transactional models with the goal of improving concurrency. Nevertheless, the quest for improvin ...

Memory Power Optimization of Java-Based Embedded Systems Exploiting Garbage Collection Information

David Atienza Alonso

Nowadays, Java is used in all types of embedded devices. For these memory-constrained systems, the automatic dynamicmemorymanager (Garbage Collector or GC) has been always a key factor in terms of the Java Virtual Machine (JVM) performance. Moreover, in cu ...

Widget-Based Approach for Remote Control Labs

Denis Gillet, Christophe Salzmann, Evgeny Bogdanov

The paper presents a novel approach to conduct laboratory experiments in relation with the Control class taught at EPFL. The existing laboratory interface built as a Java applet, which allows students to access experimentation devices locally or remotely, ...

Communix: A Framework for Collaborative Deadlock Immunity

George Candea, Horatiu Jula, Pinar Tözün

We present Communix, a collaborative deadlock immunity framework for Java programs. Deadlock immunity enables applications to avoid deadlocks that they previously encountered. Dimmunix [1], our deadlock immunity system, detects deadlocks and saves their si ...

Atomic boxes: coordinated exception handling with transactional memory

Pascal Felber, Vincent Gramoli

In concurrent programs raising an exception in one thread does not prevent others from operating on an inconsistent shared state. Instead, exceptions should ideally be handled in coordination by all the threads that are affected by their cause. In this pap ...

CITYSIM simulation: the case study of Alt-Wiedikon, a neighbourhood of Zürich City

Jérôme Henri Kämpf, Diane Perez, Darren Robinson, Urs Wilke, Maria Papadopoulou

As research in building energy demand simulation is reaching maturity, there is now a growing interest in the evaluation of the energy need of larger and/or pre-existing urban areas [1, 2, 3], to evaluate the energy performance associated with alternative ...

iProve: A Scalable Approach to Consumer-Verifiable Software Guarantees

George Candea, Horatiu Jula, Silviu Andrica

Formally proving complex program properties is still considered impractical for systems with over a million lines of code (MLOC). We present iProve, an approach that enables the generation and verification of proofs for interesting program properties in la ...
