Test failure in openam-entitlements when default locale language is not english

I've fixed it adding -Duser.language=en -Duser.region=US to the argLine parameters of the Surefire plugin, under the main pom.xml:


<java.surefire.options>-Duser.language=en -Duser.region=US -Xms256m -Xmx256m -XX:MaxPermSize=96m</java.surefire.options>

My build environment is Windows 10, Cmder with Bash (MINGW32), Oracle JDK 1.8.0_144 and Maven 3.5.0.
