Detroit通过JDK 22引入的FFM（Foreign Function and Memory）API取代老旧的JNI，以薄层实现Java与V8之间的高效通信，同时通过清晰隔离Java堆与V8堆内存，获得更好的性能和安全模型。

V8 naturally utilizes the concept of . An Isolate is an entirely separate instance of the V8 engine with its own heap, garbage collector, and event loop. In a Java environment, this allows you to spin up thousands of isolated JS sandboxes within a single JVM process, preventing a malicious or poorly written script from crashing your primary Java application. Architectural Patterns for Java V8 Addons
Improved performance and smoother textures for version 1.20+. In a Java environment, this allows you to
Within a single Isolate, you can have multiple . A Context defines a separate global scope. This allows you to run different JavaScript applications within the same engine instance without them interfering with each other's global variables. 3. V8 Values and Handles
