Codename One JamaicaVM delivers deterministic real-time Java control loops

The author explains how a customized Java virtual machine enables firm real-time control loops, such as motor drivers running at 1 kHz on a PREEMPT_RT Linux kernel, without garbage collector interference. By eliminating the JIT compiler, failing builds on unauthorized memory allocations, and using ahead-of-time compilation, the runtime achieves predictable determinism. Developers can measure performance using built-in thread statistics to verify deadlines under load. Open article →
