com.google.gson appears multiple time in matlab jar library and refuse to load new version of com.google.gson

I have encountered this problem in many times in the past years.

Matlab has several library jars with com.google.gson class, including :

C:\Program Files\MATLAB\R2016a\java\jarext\connector_impl\mgg_server\mgg_server.jar
C:\Program Files\MATLAB\R2016a\java\jarext\connector_api\connector_api_java\connector_interface.jar
C:\Program Files\MATLAB\R2016a\java\jarext\aps_impl\pubsub_impl_java\pubsub_impl.jar 

If to add customized jars to matlab which also import com.google.gson with a newer version, Matlab refuse to loaded it.

The com.google.gson class is the most frequent problems I encountered, takes about 90%.

Delete these jars sometimes solve the problem, but sometimes cause matlab internal class definition lost, such as:

>>panel = uifigure('name',obj.title,'NumberTitle','off','Visible','on','Position',obj.panelPos,...
                'MenuBar','none','ToolBar','none','resize','off');
    
MathWorks::System::IUserException [Undefined variable "com" or class "com.mathworks.matlabserver.connector.api.Connector.isRunning".
Error in connector.isRunning
Error in matlab.ui.internal.toolstrip.base.Utility.startConnector (line 363)
            isRunning = connector.isRunning;
Error in matlab.ui.internal.desktop.uicontainer.UIContainer (line 137)
            [~, this.ConnectorPort] = matlab.ui.internal.toolstrip.base.Utility.startConnector();

            this = [e-mail](htmlpath);

            this.Container = matlab.ui.internal.controller.FigureContainer;

            this.createContainer();

        obj.createView( parentController, parentView, map );

            [e-mail]( this, webComponent, parentController );
Error in matlab.ui.internal.componentframework.WebControllerFactory/create (line 87)
             component.createController( parentController, [] );]

which is localized in % C:\Program Files\MATLAB\R2016a\java\jarext\connector_api\connector_api_java\connector_interface.jar

A recommendation is to seperate the gson brach out as an isolated jar.
