When trying to setup jgroups for JDBC_PING using MariaDB, I get:

Caused by: java.lang.IllegalArgumentException: JDBC Driver required for JDBC_PING protocol could not be loaded: 'org.mariadb.jdbc.Driver'
   at org.jgroups.protocols.JDBC_PING.loadDriver(JDBC_PING.java:327)
    at org.jgroups.protocols.JDBC_PING.init(JDBC_PING.java:127)

But my liferay is running off MariaDB right now, so some sort of odd classloader issue?
