最近在用FRIDA修改安卓的的网络状态后，手机运行几个小时就出现异常，检测日志发现是JAVA的全局应用超过大小导致的，日志里出现 global reference table overflow (max=51200) ，请问要如何赋值，才能及时释放引用呢。代码是这样的：

Java.perform(function () {
    var networkInfo = Java.use("android.net.NetworkInfo");
    var netmanager = Java.use("com.android.server.ConnectivityService");
    netmanager.getActiveNetworkInfo.implementation = function () {
        var netInfo = networkInfo.$new(1, 0, "WIFI", "subWifi");
        //var netState = Java.use("android.net.NetworkInfo$State");
        var netDetailedState = Java.use("android.net.NetworkInfo$DetailedState");
        netInfo.mIsAvailable.value = true;
        netInfo.setDetailedState(netDetailedState.CONNECTED.value,null,null);
        //netInfo.mState.value = netState.CONNECTED.value;
        //netInfo.mDetailedState.value = netDetailedState.CONNECTED.value;
        //console.log("getActiveNetworkInfo2 "+netInfo.toString());
        return netInfo;
    };

打印的日志如下：
