In the sense that you cant look at a compiled class and make sure its well formed. I was talking in terms of the VM being able to do verification of the byte code, which basically means that it can make sure that the code is not ill formed, and wont cause some of the unsafe memory corruption that can happen by executing native code. I agree some of the java safety comes at the cost of (slow) runtime checks, and even the above checking while loading may be slow but it sure is safer.
