      Specify non-empty CLASSPATH when calling jboss-modules.

      [jboss-eap-6.3]$ CLASSPATH="." java -jar jboss-modules.jar -mp modules/ -dep org.picketbox -class org.picketbox.datasource.security.SecureIdentityLoginModule test

      Encoded password: 48e90df5bc00051e

      When running jboss-modules standalone with -class option, if CLASSPATH environment variable is not set, an NPE is thrown when ClassPathModuleLoader attempts to write java.class.path = CLASSPATH.
