error after first reload

---------
I am developing a Mavenized Platform application.

I have a module (module1) attached to the "app" project of the platform application as a Maven dependency. Module1 is also added as a module to the pom of the "parent" project of the platform application.

Module1 is a very simple project consisting a singleton topcomponent created with the visual designer.

When I modify the code of Module1 (say, change the background color of a label placed in the topcomponent) the following happens:

I build Module1 with "Build".
I call "Reload in target platform":

The text of menu item for the topcomponent (in the "Window" menu) disappears in the running platform application. The menu item stays there but it will not work anymore. There is an error in the "IDE Log" window (attached:error_after_first_reload.txt)

After this, Module1 somehow becomes invalid in the platform application and will not load even after a full restart of the application.

I can fix this only by running a full "Clean & Build" and calling "Reload in target platform" but I still get an error from the platform application in a dialog (attached:error_after_second_reload.txt) and an error in the "IDE log" (attached:error_after_second_reload2.txt).

After this the platform application can be restarted and will start without errors and showing the modified version of Module1.
