I am interested in opinions about the use of Java in safety critical envirnoments. I am currently supporting a system based built with ADA. Migration to Java is proposed. Are there any special Java characteristics to be wary of? Any reservations for Java in a saftety critical environment?

Are there any special Java characteristics to be wary of? Any reservations for Java in a saftety critical environment? Well, there are the obvious ones, like the lack of subtypes. And if latency matters, the fact that Java /must/ use a garbage collector can be a problem, as can the fact that all non-elementary data must be allocated from the heap. Part of the performance loss, however, is gained back by modern Java technology, which observes the program in action for a while, and then does an optimized compile on the fly. But Java learned a great deal from Ada, and does not have most of the bad things that Ada also does not have, and has many of the good things that Ada does. -- John W. Kennedy "The bright critics assembled in this volume will doubtless show, in their sophisticated and ingenious new ways, that, just as /Pooh/ is suffused with humanism, our humanism itself, at this late date, has become full of /Pooh./" -- Frederick Crews.
