如何补一个返回 HashMap 的环境？

这样子补环境，执行的时候会报错。

{
    @Override
    public DvmObject<?> getStaticObjectField(BaseVM vm, DvmClass dvmClass, String signature) {
        switch (signature) {
            case "com/android/internal/os/PowerProfile->sPowerItemMap:Ljava/util/HashMap;":
                Map<Object,Object> map = new HashMap<Object,Object>();
                map.put("battery.capacity",5000.0);
                return ProxyDvmObject.createObject(vm, map);

    }
        return super.getStaticObjectField(vm, dvmClass, signature);
}

报错如下：

JNIEnv->FindClass(java/util/Map) was called from RX@0x401a7190[libpdd_secure.so]0x1a7190
JNIEnv->GetMethodID(java/util/Map.get(Ljava/lang/Object;)Ljava/lang/Object;) => 0x7f03ab0a was called from RX@0x401a7200[libpdd_secure.so]0x1a7200

似乎是 methoid 的问题？

if (dvmMethod == null) {
    throw new BackendException("dvmObject=" + dvmObject + ", dvmClass=" + dvmClass + ", jmethodID=" + jmethodID);
}

不知道怎么解决，也查不到返回 HashMap 的示例！
