Using Sun’s Java Real-Time System to Manage Behavior-Based Mobile Robot Controllers
Journal of Robotics, 2011 Implementing a robot controller that can effectively manage limited resources in a deterministic, real-time manner is challenging. Behavior-based architectures that decompose autonomy into levels of intelligence are popular due to their robustness but do

Abstraction and Verification of Properties of a Real-Time Java [PDF]
, 2013 We present a tool for analysing resource sharing conflicts in multithreaded Java programs. Java programs are translated to timed automata models verified afterwards by the Uppaal model checker. Analysed programs are annotated with timing information indicating the execution duration of a particular statement.

Overview of Real-Time Java Computing [PDF]
Journal of Computing Science and Engineering, 2013 This paper presents a complete survey of recent techniques that are applied in the field of real-time Java computing. It focuses on the issues that are especially important for hard real-time applications, which include time predictable garbage collection, worst-case execution time analysis of Java programs, real-time Java threads scheduling and ...

Kipu – Lightweight threads for Java
Interfases, 2014 This paper describes a cooperative thread scheduling mechanism, which can be used effectively on real-time java virtual machines. This scheduler is implemented using a heap-based priority queue which allows for O(log N) processing time.

DJXPerf: Identifying Memory Inefficiencies via Object-centric Profiling for Java [PDF]
arXiv, 2021 Java is the "go-to" programming language choice for developing scalable enterprise cloud applications. In such systems, even a few percent CPU time savings can offer a significant competitive advantage and cost saving. Although performance tools abound in Java, those that focus on the data locality in the memory hierarchy are rare.

Safety-Critical Java: Level 2 in Practice [PDF]
Concurrency and Computation: Practice and Experience 29 6 2017, 2018 Safety Critical Java (SCJ) is a profile of the Real-Time Specification for Java that brings to the safety-critical industry the possibility of using Java. SCJ defines three compliance levels: Level 0, Level 1 and Level 2. The SCJ specification is clear on what constitutes a Level 2 application in terms of its use of the defined API, but not the ...

Cost Analysis for Real-time Java Scoped-memory Areas [PDF]
Journal of Systemics, Cybernetics and Informatics, 2007 Java has recently joined C and C++ as a development platform for real-time and embedded applications. Java's garbage collection, while generally a useful feature, can be problematic for these applications: garbage collection occurs at unpredictable times
