Hello, I understand that there are some disadvantages to using JNI: - difficult to debug runtime error in native code. - potential security risk. - errors in JNI code take down the entire JVM and don't provide any mechanism for graceful recovery - heavy - all queries use string I am trying to understand these disadvantages better. Could someone elaborate on each of these points and point me to examples/references? Thanks MC

Do not look for JNI disadvantages. Look for the issues that pops with bad coding in c or c++, what ever you will find more or less applicable to JNI as well.
