need a studio widget support for jdbc driver choose field :
From the code in WidgetTypeMapper in studio code for tck integration, not support use MODULE_LIST for jdbc driver choose in tck. So a feature. And another issue then: How to make it works for cloud?
And at runtime, we will use some inside maven dependency resolver to load that driver classes.
About cloud, cloud platform also need to provide a new ui widget for setting jar maven gav/path which exists in its .m2. Or a text table is enough, user need to set the path string self instead of choosing in a list. Also need to support new widget for tck : "Module", which help studio to decide ui(sure cloud platform no that now).
