You are right. I should have been more clear. I am talking about the bog standard one that most people use from Oracle/OpenJDK. A long time back it was called "HotSpot JVM". That one has source code available on GitHub. It is mostly C++ with a little bit of C and assembly.

Define mostly, https://github.com/openjdk/jdk

- Java 74.1%

- C++ 14.0%

- C 7.9%

- Assembly 2.7%

And those values have been increasing for Java with each OpenJDK release.

JDK≠JVM

If you are only talking about libjvm.so you would be right, then again that alone won't do much help for Java developers.

That is what most people are talking about when they are discussing the JVM, yes
