Errai 2.4.4.Final with GWT 2.6.0

[luca.masini]

Hi guys, I'm trying to convert a project to GWT 2.6.0 and I would like to know if someone was successful in this.

When I switched changing my maven properties to:

<gwtVersion>2.6.0</gwtVersion>
<errai.version>2.4.4.Final</errai.version>   
<maven.compiler.target>1.7</maven.compiler.target>   
<maven.compiler.source>1.7</maven.compiler.source> 

I was unable to compile due to this Exception (cutted for readability):

The strange thing is that it happens always as second, if I run the code-server then I got that with install and viceversa.

I cleaned everything and tried upgrading guava to 16.1, but still having this.

Thank you for your support.

Hi Luca,

Can you share the full stack trace? It looks like there are some lines missing.

Hi Luca,

Unfortunately I still don't see any hint as to what causes this error. It fails to load the generated ServerMarshallingFactoryImpl class. I can't see how this relates to upgrading to GWT 2.6.0 either as we have done that many times now. The class ServerMarshallingFactoryImpl seems to be missing or contain references to classes that can't be loaded.

The only advice I have is to look for more error messages on your console and to configure the compiler to use strict mode (add <strict>true</strict> in your gwt-maven-plugin configuration). The latter should hopefully provide you with more error information.

Cheers,

Christian
