GWT 2.7 Super Dev Mode and IntelliJ 14

I'm trying to do a pretty simple test of GWT's Super Dev Mode and IntelliJ 14 (138.2458.8). Specifically, I want to see the file-by-file recompilation working, and then demo it to my co-workers.

To do this, I did a git clone of the gwt repository and then built it.

After it was all done, I loaded the showcase sample into IntelliJ 14, created a project around it, and got things setup with a run configuration for "old" Dev Mode. So far, so good. It runs, the showcase comes up as expected.

Now, I created another run configuration, but this time, I clicked the "Use Super Dev Mode" check box. When I try to run this configuration, however, I'm getting this error:

I'm guessing that the issue has to do with whatever is outputting the "Running GPE launcher for GWT-2.6.x version" message, but I'm not sure.

For both run configurations, I:

• Unchecked the "Open in browser"
• Added "-bindAddress 0.0.0.0" to the "Dev Mode parameters"

Is this case supposed to work? Or is the GWT 2.7 support not yet fully supported?
