> The same is true of a middle-of-the-road language like Java, but Java isn't ideally suited to kernel development. (If OS researchers prove me wrong on this point, then that's great, of course.) Microsoft had an experimental OS called Singularity [1] --- start quote --- The lowest-level x86 interrupt dispatch code is written in assembly language and C. Once this code has done its job, it invokes the kernel, which runtime system and garbage collector are written in Sing# (an extended version of Spec#, itself an extension of C#) and runs in unprotected mode. --- end quote --- And don't forget that SIM cards in your phone run a Java... -ish [2,3] [1] https://en.wikipedia.org/wiki/Singularity_(operating_system) https://en.wikipedia.org/wiki/Singularity_(operating_system) [2] https://www.defcon.org/images/defcon-21/dc-21-presentations/Koscher-Butler/DEFCON-21-Koscher-Butler-The-Secret-Life-of-SIM-Cards-Updated.pdf https://www.defcon.org/images/defcon-21/dc-21-presentations/...
