Any V8 object instantiated in Java must be explicitly closed using try-with-resources blocks or explicit .close() statements. Failing to do so will result in a native memory leak that the JVM Garbage Collector cannot clean up. Thread Safety V8 is fundamentally single-threaded per isolate (context).
