Bruno Oliveira sure thing. Here are the steps:

1. build master of https://github.com/aerogear/aerogear-parent
2. build "Keycloak_1.1.-beta2" branch of https://github.com/matzew/aerogear-unifiedpush-server
3. start Wildfly 8.2.0
4. copy the H2 database file to /JBoss/wildfly-8.2.0.Final/standalone/deployments
5. cp servers/auth-server/target/auth-server.war /JBoss/wildfly-8.2.0.Final/standalone/deployments

the deployment of the auth-server.war file will give you the stack-trace described earlier
