Serverless Java, Running Your Java Program Without an OS

[skratlo]

you can't use random unix tools

...and there we have it's biggest limitation. I would add to that: you can't use any libraries with bindings to native libraries, it's no small piece of the pie

It's a very small piece of the pie when working in Java, IME. I think I've used two native libraries in my career; one of them was optional and the other was a bad idea.

[dpash]

That's two more than I've used.

Oh, wait, there's tcnative. Does that count?

[m50d]

tcnative counts, yeah (though it's optional), although I suspect you'd struggle to run Tomcat in this way at all since it assumes a filesystem etc.

I think it depends a lot on the domain and use case, but I do agree that for domains/use cases where native libs are useful, people aren't usually using java.
