On the other side of the spectrum, companies highly averse to technical changes culturally (typical case in the F500) will avoid ever upgrading kernels, libraries, and tooling. It's how I've wound up spending days trying to compile C++11 and C++14 code with toolchains that would run on CentOS / RHEL 5 and 6. Using the JVM lets you side-step the shared library linkage compatibility issues at least, but when you need a new kernel for instrumentation it's an even harder sell to an antagonistic IT department that only wants 2 OSes and corresponding versions to exist in the world ideally - "Linux" and Windows.
