Submission Requirements.

Participants are expected to submit a paper of at most 10 pages (ACM Conference Format, i.e., two-columns, 10 point font). 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 the JTRES.

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

appendix. The source version for the published paper will be hosted at the JTRES web site.

Accepted papers will be invited for submission to a special issue of the Journal on Concurrency and Computation: Practice and Experience.

Over 90 percent of all microprocessors are now used for real-time and embedded applications, and the behavior of many of these applications

is constrained by the physical world. Higher-level programming languages and middleware are needed to robustly and productively

design, implement, compose, integrate, validate, and enforce real-time constraints along with conventional functional requirements

and reusable components. It is essential that the production of real-time embedded systems can take advantage of languages, tools,

and methods that enable higher software productivity. 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 it features good software engineering characteristics, standard Java is unsuitable for developing real-time embedded

systems, mainly due to under-specification of thread scheduling and the presence of garbage collection. These problems are addressed by

the Real-Time Specification for Java (RTSJ). The intent of this specification is the development of real-time applications by

providing several additions such as extending the Java memory model and providing stronger semantics in thread scheduling.

Interest in real-time Java in both the research community and industry has recently increased significantly, because of its

challenges and its potential impact on the development of embedded and real-time applications. The goal of the proposed 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 experiences gained by researchers.

This year following two topics are of special interest: 

    * Open source solutions

    * Multiprocessor and distributed real-time Java

Open source software and hardware solutions have received growing attention in recent years; major vendors of Java technology have

adopted the open source development model for some of their products. Open source development benefits from distributed peer review and

transparency and enables easy verification of published results. Access to the source code also stimulates building upon prior work,

as it allows to reuse tested and reviewed components.

Nowadays, real-time systems demand more functionality than in previous years. Consequently the execution platforms are often

multiprocessors or distributed systems. Although the Real-Time Specification for Java has addressed some multiprocessor issues,

other issues are still outstanding. Furthermore, defining the appropriate RTSJ abstractions for distributed real-time programming

is still an open topic. One day of the workshop will be designated for multiprocessor and distributed systems issues with papers, panels

and invited presentations.
