Java, like .NET, are just solid application platforms which are statically typed and their performance is good. Java has a history in big systems for soon 30 years. Rust, Python and Go are just not there yet. Rust is too low level, Python is not statically typed and will always suffer performance wise and Go ... I is a youngster :). And .NET is always not everyone's free choice. And Apache, well they just liked Java for their applications. They started with some C/C++ code but then quickly aggregated a lot of Java tech.
