Java Addon V8 -

Garbage collection in Java does not automatically clean up native V8 objects. If you instantiate a V8Object or V8Array inside Java, you close it. Always wrap your V8 resources in a try-with-resources block or explicitly call .close() / .release() . Failure to do so will result in a native memory leak that can crash your JVM. 2. Thread Safety

Use try-with-resources style or explicit blocks.

Use a ThreadLocal or a blocking queue pool to lease runtime instances to incoming worker threads. Script Caching and Compilation Java Addon V8

try (V8 v8 = V8.createV8Runtime()) int result = v8.executeIntegerScript("var a = 10; var b = 20; a + b;"); System.out.println("Result: " + result); // Output: Result: 30

In this example, when the JavaScript code executes print('hello...') , it triggers the Java callback, which then prints the message to the system console.

V8 isolates are thread-safe. Never share a V8 runtime across threads. Instead, use a pool of runtimes (one per thread) or serialize access via synchronized . Each runtime has its own native heap. Failure to do so will result in a
