Re: Issue while upgrading to to GWT 2.5RC build

[Ajax]

You might have a corrupt gwt-user.jar; if your SHA checksum doesn't match the one from code.google.com/p/google-web-toolkit/ then you should unzip a fresh copy.

Either that, or your IDE is recompiling the classes as the builder is running, so it gets an IO exception when trying to lookup classes.

A good rule of thumb, if you have Build Automatically enabled in your IDE, don't save any files until your compile hits the Compiling Permutations stage.
