The vast majority of which where actually in parts of the C++/C code used to implement the most popular implementation of the JVM. Which is in C++ for historical reasons not because C++ is needed to implement a JVM. And as other commenters note the amount of C++ decreases each release because its less and less useful to have any code in the JVM as C++. In graal calls to the OS are going to more limited in surface area than in Hotspot C2. For all reasons removing a class of errors e.g. buffer overflow leading to executable code is going to give more secure code. Not that I think Java is a silver bullet that will solve all problems. I do think that a language like Java or Rust is a major improvement over C with minimal performance issues.
