I recently upgraded to GWT 2.6.1 and I see errors like below randomly at startup in DevMode. I saw this issue before the upgrade but it seems worse now. It does not happen all the time, it seems to occur when there is a delay in the DevMode starting.
E.g. I will see this in the console... Dev Mode initialized. Startup URL: http://127.0.0.1:8888/index.html?gwt.codesvr=127.0.0.1:9997 ...and then there is a very long pause before 'Debug enabled' appears in the console. During this time the browser gives the busy/non-responding feedback and often will display the browser hung dialog box to which I select the continue option. I'm using Firefox 24.2 and have been for some time as that works with DevMode. This behavior does not happen all the time and I have not been able to determine what/when it will occur but it seems to occur more often now with 2.6.1.
