因为hessian 序列化只支持HashMap，详见：com.alibaba.com.caucho.hessian.io.MapSerializer#writeObject(Object obj, AbstractHessianOutput out)

if (cl.equals(HashMap.class)
    || ! _isSendJavaType
    || ! (obj instanceof java.io.Serializable))
      out.writeMapBegin(null);
    else
      out.writeMapBegin(obj.getClass().getName());

The native Map from jdk is ok
But com.google.common.collect.SingletonImmutableMap is from guava， the map initialize method is different。

So occurs bug

```java
@Test
public void testImmutableBiMapSerializer() throws Exception {
Map map = new ImmutableMap.Builder()
.put(30, "30")
.put(43, "30").build();
Map deserialize = baseHessianSerialize(map);
Assert.assertTrue(deserialize.equals(map));
}

```log
com.alibaba.com.caucho.hessian.io.HessianProtocolException: 'com.google.common.collect.ImmutableMap$SerializedForm' could not be instantiated

@lovepoem Do we have anything to do with this issue?

[lovepoem]

The native Map from jdk is ok
But com.google.common.collect.SingletonImmutableMap is from guava， the map initialize method is different。

Do we have anything to do with this issue?

No，it's not very easy to support the special Map from guava, I suggest to use Map from jdk in the business interface

[ralf0131]

ok, I am closing it now.

[ivanhjc]

Dubbo has a problem in parsing com.google.common.collect.ImmutableMap right? When I pass this map

Map<String, Object> filter = ImmutableMap.of("cusId", 56284, "sceneType", 5);

to a service the received map is deserialized as this {"keys":["cusId","sceneType"],"values":[56284,5]}. Is this problem solved yet? Since I've used ImmutableMap a lot.
