I don't think I would call JEE and Spring a failure.
They mark the turning point I stopped worrying about UNIX deployments.
An application server has all the features I care about from a container, including fine grain control over which apis are accessible to the hosted applications.
It doesn't matter if the application server is running on the OS, an hypervisor, container or even bare metal.
Back in 2011 we were already using AWS Beanstalk for production deployments.
Also OS/400 is like that, user space is bytecode based. For writing kernel space native code, or privileged binaries you need the appropriately called Metal C compiler.
