Hermes' README tells you you need ICU 4.6. It happens gwt-dev.jar contains
ICU (because that's what's used by GWT to generate the client-side code for
I18N, and thus what Hermes uses to replicate the functionality on the
server side), and DevMode tells you that you're missing ICU in your
WEB-INF/lib (which means your app won't run when deployed to a web server)
but it can temporarily help you by adding gwt-dev.jar to the classpath (as
if it were within the WEB-INF/lib, which is a very very bad idea and can
cause all sorts of breakages).
The idea behind this warning is to warn you in case you added a JAR to your
classpath (e.g. build path in Eclipse) but didn't put it in the
WEB-INF/lib. It happens that in your case you didn't put anything anywhere,
but the classes you're trying to use (via Hermes) happen to be in GWT
already.
So, yes, it's a serious warning. Download ICU 4.6 and put it in your
WEB-INF/lib (oh, and update to GWT 2.6, GWT 2.5 is more than 1 year old
already!)
