Abstract
JTime is a commercial offering from TimeSys, Inc. implementing the Real-Time Specification for Java (RTSJ). We have been experimenting with and benchmarking JTime for a number of months and report some precise time measurements of the predictability, repeatability, and accuracy of JTime’s implementation of some key RTSJ constructs. In particular, we have measured the interarrival times between subsequent releases of the waitForNextPeriod() method call (in three different thread contexts) and for instances of PeriodicTimer. We also measured latencies for the above constructs and for instances of AsyncEventHandler. We find, in general, that the results are very good and that applications with hard real-time constraints can be accommodated. We further note that these results are obtained using the interpreted version of JTime and would expect significantly better results with pre-compilation.
