I seem to remember having seen somewhere that this issue is due to how Java 7 deals with generics.

Unless you use Java 7 language features, try passing -sourceLevel 6 to the GWT compiler (or DevMode).

 

I'm not sure if I can use guava 15.  Errai pulls in version 14, I think.

Guava has a clear compatibility policy, so unless Errai uses @Beta or @Deprecated APIs from Guava 14, it should Just Work™ with Guava 15. 

Thank you Thomas. 

It looks that sourceLevel is being ignored. I've tried -sourceLevel 6 , sourceLevel XX ... nothing.

My default JDK is 1.6 , but also proved on JDK 1.7. 

Always getting the same exception .
