I&#x27;ll be nice since you are. Java is well-defined language with safety features. Problem was it&#x27;s written for inefficient abstract machine hard to implement correctly and with much complexity. That and its libraries are written in an unsafe language.<p>Whereas, languages like Modula-3, Ada, or safe variants of C are straight-forward to map to real hardware with small to no runtimes and libraries in same language. Many checks in by default. Two, C subsets and SPARK, can be proven free of common errors.<p>There&#x27;s a vast difference in safety between such languages and the Java platform. Complexity of compiler&#x2F;runtime and unsafe libraries are main reasons. Safety-critical, minimal runtimes exist for Java but they&#x27;re slow and I doubt you paid $$$ for them. ;)
