We recently decided to integrate Material Design into our mature GWT 
application and this has finally forced our hand on moving from Legacy dev 
Mode to Super dev mode. We have this working fairly well using Chrome and 
Intellij IDE, 2016.2. One lingering problem though is viewing Java 
containers (Lists, Maps, etc.) in the debugger. In the screenshot below, 
the two expanded *supportingCopyWidgetPresenters* and 
*supportingCopyEventPageBlockContentElements* are both declared as 
*java.util.Lists*:

In case this is hard to read, the debugger is showing both lists values to 
be:

array = Internal error: com.google.gson.JsonParseException: Expected 
BEGIN_ARRAY but was BEGIN_OBJECT at line 1 column 1386

Is there a special argument I need to pass to super dev mode to have it 
interpret Lists (and Maps, for that matter) correctly in the debugger? Is 
this a matter of telling super dev mode to use a different JSON parser?


Any help is greatly appreciated!
