A well-repacked V8 addon runs the JavaScript code in an isolated isolate (V8’s term for a sandbox). This prevents malicious scripts from accessing the host JVM’s file system or memory directly.
To verify the safety of a "Java Addon V8 Repack": java addon v8 repack
While V8 can be called directly from JNI, a dedicated wrapper (e.g., J2V8’s C++ layer) simplifies object lifetime management and exception handling. The repack may include prebuilt wrapper code compiled against the specific V8 version. A well-repacked V8 addon runs the JavaScript code

Because V8 is written in C++, objects allocated in JavaScript will not be garbage collected by the JVM. Always call v8.release() on runtime and Object.release() on arrays and objects.
Solution: Use try-with-resources patterns or finalize wrappers.
