解决了 出错问题是底层quickjs释放jsValue变量的时候找不到这个 jsValue报了空指针 原因是因为 quickJs是线程不安全 的，特别是在创建jsValue的时候 比如说我在quickJs里面开启了一个新的线程处理一些事情，之前我直接在新线程里面创建jsvalue并回调回来，可能几次没有事情，但是执行次数多了就会报这个问题。 后面我改成在新线程里面回调回默认的quickJs-1的线程就没有出现这个问题了

多谢大佬解答，我使用的时候都是在主线程的，没有使用新的线程，下面是我的用法：
mQuickJS = QuickJS.createRuntimeWithEventQueue();
mJsContext = mQuickJS.createContext();
mJsContext.registerJavaMethod()
JSObject jsObject = mJsContext.executeObjectScript(javaScript, null);
if (jsObject instanceof JSFunction) {
JSFunction jsFunction = (JSFunction) jsObject;
if (!jsFunction.getContext().isReleased()) {
JSFunction callback = new JSFunction(mJsContext, new JavaVoidCallback() {
@Override
public void invoke(JSObject receiver, JSArray args) {
}
});
JSArray jsArray = new JSArray(mJsContext).push(JSUtils.getParams(mJsContext, methodParam)).push(callback);
jsFunction.call(null, jsArray);
}
}
我这样使用OK吗？大佬是怎么使用的？能否贴个示例，多谢
mJsContext.registerJavaMethod(new JavaVoidCallback() {
@Override
public void invoke(JSObject receiver, JSArray args) {
});
}
}, "exit");
另外测了下，这里的 invoke 方法是在 quickJs-1 线程，我把这里的内容抛回主线程还是有这个问题
