dockerClient.inspectContainerCmd(id).exec() throws exception. version 3.5.1 #2457

when i exec this ,
InspectContainerResponse inspectResponse = dockerClient.inspectContainerCmd(id).exec();

throws exception , like this.
java.lang.RuntimeException: com.fasterxml.jackson.databind.exc.ValueInstantiationException: Cannot construct instance of com.github.dockerjava.api.model.Ports, problem: Error parsing ExposedPort '161/udp/tcp'
at [Source: UNKNOWN; byte offset: #UNKNOWN] (through reference chain: com.github.dockerjava.api.command.InspectContainerResponse["HostConfig"]->com.github.dockerjava.api.model.HostConfig["PortBindings"])

Then, my container's info , 'HostConfig' likes this.
"HostConfig": {
"Binds": [

        ],
        "ContainerIDFile": "",
        "LogConfig": {
            "Type": "json-file",
            "Config": {}
        },
        "NetworkMode": "host",
        "PortBindings": {
            "161/udp/tcp": [
                {
                    "HostIp": "0.0.0.0",
                    "HostPort": "161"
                }
            ]
        },
 ......

From the error message, it can be seen that the port binding ‘161/udp/tcp’ parsing error occurred.
How to solve it?
