Answer 1

Difficult to debug runtime error in native code

Have you ever seen a stacktrace in Java? Well they are very user friendly and they tell you most of the times, the line number, class method and what failed. You don't have those on Native code.

Errors in JNI code take down the entire JVM and don't provide any mechanism for graceful recovery

When you run java code, all is run under the control of the JVM, if something goes wrong, the JVM can handle it. You don't have that control using Native code.
