Use log4j-1.2 instead of log4j-1.2.16

/usr/share/java/log4j-1.2.jar is a symlink to the newest release of
log4j 1.2 installed on the system. Our systems have log4j-1.2.17
installed, but not log4j-1.2.16, causing the build to fail.

This change adds the symlink instead of the 1.2.16 jar file to avoid
this problem
