MOTIVATION

Over 90% of all microprocessors are now used for real-time and
embedded applications. Embedded devices are deployed on a broad
diversity of distinct processor architectures and operating
systems. The application software for many embedded devices is custom
tailored if not written entirely from scratch. The size of typical
embedded system software applications is growing exponentially from
year to year, with many of today's embedded systems comprised of
multiple millions of lines of code. For all of these reasons, the
software portability, reuse, and modular composability benefits
offered by Java are especially valuable to developers of embedded
systems.

Both embedded and general purpose software frequently need to comply
with real-time constraints. Higher-level programming languages and
middleware are needed to robustly and productively design, implement,
compose, integrate, validate, and enforce memory and real-time
constraints along with conventional functional requirements for
reusable software components. The Java programming language has become
an attractive choice because of its safety, productivity, its
relatively low maintenance costs, and the availability of well trained
developers.

Although Java features good software engineering characteristics,
traditional Java virtual machine (JVM) implementations are unsuitable
for deploying real-time software due to under-specification of thread
scheduling and synchronization semantics, unclear demand and
utilization of memory and CPU resources, and unpredictable
interference associated with automatic garbage collection and adaptive
compilation.

GOAL

Interest in real-time Java by both the academic research community and
commercial industry has been motivated by the need to manage the
complexity and costs associated with continually expanding embedded
real-time software systems. The goal of the workshop is to gather
researchers working on real-time and embedded Java to identify the
challenging problems that still need to be solved in order to assure
the success of real-time Java as a technology and to report results
and experience gained by researchers.

The Java ecosystem has outgrown the combination of Java as programming
language and the JVM. For example, Android uses Java as source
language and the Dalvik virtual machine for execution. Languages such
as Scala are compiled to Java bytecode and executed on the JVM. JTRES
welcomes submissions that apply such approaches to embedded and/or
real-time systems.

TOPICS OF INTEREST

Topics of interest to this workshop include, but are not limited to:

- New real-time programming paradigms and language features
- Industrial experience and practitioner reports
- Open source solutions for real-time Java
- Real-time design patterns and programming idioms
- High-integrity and safety critical system support
- Java-based real-time operating systems and processors
- Extensions to the RTSJ and SCJ
- Real-time and embedded virtual machines and execution environments
- Memory management and real-time garbage collection
- Scheduling frameworks, feasibility analysis, and timing analysis
- Multiprocessor and distributed real-time Java
- Real-time solutions for Android
- Languages other than Java on real-time or embedded JVMs
- Benchmarks and Open Source applications using real-time Java

SUBMISSION REQUIREMENTS

Participants are expected to submit a paper of at most 10 pages (ACM
Conference Format, i.e., two-columns, 10 point font). Industrial
experience and practitioner reports may be submitted as 4-page short
papers with no page limit for references cited. Accepted papers will
be published in the ACM International Conference Proceedings Series
via the ACM Digital Library and have to be presented by one author at
JTRES.

LaTeX and Word templates can be found at:
http://www.acm.org/sigs/pubs/proceed/template.html

The ISBN number for JTRES 2015 is TBD.

Papers describing open source projects shall include a description how
to obtain the source and how to run the experiments in the appendix.

Papers should be submitted through Easychair. Please use the
submission link: https://easychair.org/conferences/?conf=jtres2015

The best papers will be invited for submission to a special issue of
the Journal on Concurrency and Computation: Practice and Experience,
as determined by the program committee.
