RAII doesn't save you from buffer overflows, or memory leaks when you need an object to live beyond the current scope. C arrays and pointers can still be used on the stack, and are sometimes simply the right tool for the job. While RAII greatly reduces memory leaks and enhances resource-management, it doesn't save you in all cases, which means there still is an overhead and you will still have to worry about it. Java doesn't have Undefined Behaviour, buffer overflows, or memory leaks (not completely true, I'm not counting space leaks here but I hear it's possible to introduce a memory leak by writing a faulty class loader). While C++ does provide idioms for writing safe code, C++ can't remove them, which means you will always have to worry about it. Sometimes the problem isn't actually your code, but the library you're using, which is the case at my job, which again made me miss a safer language :(
