Hi Bruce,
This may be a problem with JUnit + GWT rather than anything specific to SmartGWT / SmartClient.

Firstly - we're interested in what is prompting the upgrade - are there specific features of GWT 2.7 you require?

One thing to be aware of - as of GWT 2.7, GWT no longer supports script tags embedded in .gwt.xml files automatically to inherit JS files into your application.

This is the mechanism SmartGWT uses in the SmartGWT.gwt.xml and SmartGWTNoTheme.gwt.xml modules to inject the SmartClient library JavaScript into the page.
You will need to instead inherit SmartGWTNoScript and ensure your bootstrap HTML file includes explicit "<script src=..." tags in the header.

This would also be true for any other GWT module imports which make use of scripts injected in this way.

The stack traces you shared do indicate a JavaScript error from a missing variable - that may be a result of failing to load some require resource, whether the SmartClient JavaScript libraries or something else, so resolving this problem may solve things for you.

Note: If you are hitting this problem, you should see warnings in the compile time logs.

If this doesn't give you enough to get things working, we have seen a case where a normal (non SuperDevMode) compilation was required before SuperDevMode was usable. You might want to try that (simply compile the entire application, before doing a SuperDevMode compile).

If neither of these suggestions work, and you are unable to get anywhere from searching the JUnit / GWT knowledgebases, we'll need some more information to comment further.

The ideal is always for us to see a runnable test case that demonstrates the problem which we can debug on our end.

If this isn't possible, as much information as you can share on what exactly your project is doing that leads to the error, and any compile time logs and runtime logs generated when you hit the error (feel free to use the support@isomorphic.com address for these if they are unwieldy to post here).

We'd like to upgrade to GWT 2.7 in order to switch to SuperDev mode

Inheriting SmartGWTNoScript will not work because we don't use an html page. Instead we're using JUnit. This problem does not happen in the production build, only in unit tests.

How is compile logging enabled?

If you're compiling your SGWT project via command line, compile time logs should be output directly to the shell. If you're using Eclipse, you should see compile time logs showing up in the Console window.
(If you have another setup, you may need to consult GWT's documentation, or clarify what you are doing).

A couple of other comments:
- Super Dev Mode is available in 2.6.1 - you shouldn't need to upgrade to 2.7 to make use of it, it's just a little more user friendly.
- if you can't glean any useful information from the logs, a way to reproduce the problem (a test case we can run on our end) would be a good way to
