Region-based memory management: An evaluation of its support in RTSJ

Memory management is a source of unpredictability in the execution time of Java programs. This is because garbage collection introduces possibly unbounded blocking pauses to threads, which is unacceptable in real-time systems. To cope with this problem, the Real-Time Specification for Java (RTSJ) ad...

This is because garbage collection introduces possibly unbounded blocking pauses to threads, which is unacceptable in real-time systems. To cope with this problem, the Real-Time Specification for Java (RTSJ) adopts a region-based approach which relies on memory scopes that are automatically freed upon termination of their lifetime.
