Hello all, I can now confirm the 1.7.1 gwt-servlet.jar file was being used in my WEB-INF/lib folder output by IntelliJ IDEA 9.0.1.
I thought I had removed all references to 1.7.1 from IntelliJ when I updated to 2.0.2, but since JetBrains have introduced these new, darn- fangled "artifacts" in IntelliJ 9.x, there is now one more place to look and check for library files -- as if there wasn't enough places in IntelliJ already... So, while I used 2.0.2 gwt-user.jar and gwt-servlet.jar as dependencies when compiling I had errantly not checked the new artifacts configuration in the project structure, which is where the files output to WEB-INF/lib are specified. So, in the end, the error messages were all my fault <red-faced> and I deeply apologise for wasting everybody's time. Besides checking for everything myself, what really clued me in was the link Trevor Skaife provided: http://www.google.com/url?sa=D&q=http://code.google.com/p/google-web-toolkit/issues/detail%3Fid%3D4363%26q%3DParameter%25200%2520of%2520is%2520of%2520an%2520unknown%2520type&usg=AFQjCNFpbG55iGzVS5lAa1o1iTL4tFa88g particularly at the end, where Thobias Karlsson says things worked for him when he removed the gwt-servlet.jar from WEB-INF/lib and assumed (correctly) that the one sitting there previously was an older version of gwt-servlet.jar. My solution wasn't to remove it entirely, just be sure the correct version is there! That's the problem with using these modern IDE's, you tend to lose some control. I miss good ol' UNIX 'make' when I used to be a 'C' programmer <mumble,mumble> years ago! Thank you to EVERYONE who participated in this discussion. All your comments did help, because I started to realise it was something *I* was doing wrong after all. In the end, I really couldn't believe GWT was up to 2.0.2 with a problem like this one, but I do see others stumbling over it too. Hopefully this discussion is helpful to those others in this respect.
