JTRES 2011 - The 9th Workshop on Java Technologies for Real-Time and Embedded System

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.
