Integrity is a cornerstone of the Java Platform as it enables/bolsters reliability, maintainability, security, and performance. But there are operations that undermine it: deep reflection with setAccessible, Unsafe, native code, and agents allow code to break many of Java’s promises. Now, OpenJDK wants to lock them down by default, requiring command-line options like --enable-native-access to enable them, thus ensuring the platform has integrity by default while application operators can still make the choice to trade that away if the benefits are worth it.
