This is true even with most SV darlings. Netflix, Google, Uber, and Amazon use tons of Java. Probably the majority of their systems.
Microsoft is an exception because they built C# which is basically a more modern but less popular variant of Java. There was even a project for a long time that let you use Java code in C# projects by converting the bytecode, they're that similar.
The notable exception is Facebook. They were stuck in PHP hell for so long that they redesigned the language to make it work.
I'd say that you find a fair share of C++ as well. Especially for high volume endpoints.
Easy to find out just by looking at their open job positions.
