Hi all, I am integrating the oxd client API [https://github.com/GluuFederation/oxd](https://github.com/GluuFederation/oxd) to achieve the social (Google) login. When I run the following class: [https://github.com/GluuFederation/oxd/blob/master/oxd-client/src/test/java/org/xdi/oxd/client/manual/GoogleTest.java](https://github.com/GluuFederation/oxd/blob/master/oxd-client/src/test/java/org/xdi/oxd/client/manual/GoogleTest.java) I am getting the following error on my console: ``` /usr/lib/jvm/java-8-oracle/bin/java -agentlib:jdwp=transport=dt_socket,address=127.0.0.1:34735,suspend=y,server=n -Dfile.encoding=UTF-8 -classpath
