About 15 years of Real-Time Java']Java

Java is an object oriented programming language introduced by Sun Microsystems in 1995. From this date, Java has received a high interest from both industry actors and researchers. Java presents many benefits such as reliability of code, portability because its neutral architecture, and security in distributed environments, which leads it a privileged technology to develop embedded and distributed applications. Even though Java has issues as threads and automatic garbage collection, it has problems regarding its use in real-time systems, which must be solved. Since 1997 several research works has been focused on the limits of the Java language and its execution environment to seek the possibility for real-time technology using Java. This paper outlines and discusses the investigated issues and the developed supporting technology that allows the construction of real-time systems using Java.
