He's doing this because log4j tries to initialize his new appender and will
throw a ClassNotFoundException as the Hadoop & Zookeeper jars set by
`general.classpaths` are loaded later in Java by the Accumulo classloader.
While `general.classpaths` should available to users, it should be empty by
default and the classpath required for Accumulo should be built in
`accumulo-env.sh` before `java` command is called.
