lovepoem commented on issue #280: dubbo 序列化问题.有谁遇到过吗
URL: https://github.com/apache/incubator-dubbo/issues/280#issuecomment-405533132
 
 
   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<Integer, String> map = new ImmutableMap.Builder<Integer, String>()
                   .put(30, "30")
                   .put(43, "30").build();
           Map<Integer, String> deserialize = baseHessianSerialize(map);
           Assert.assertTrue(deserialize.equals(map));
       }
   ```
   ```log
