[Building Sakai] Too many copies of log4j.jar ??

[Charles Severance]

I am playing with the 2-9-x branch and there are too many log4j jar files:

./common/lib/log4j-1.2.16.jar
./components/profile2-pack/WEB-INF/lib/log4j-1.2.14.jar
./webapps/accountvalidator/WEB-INF/lib/log4j-1.2.14.jar
./webapps/mailsender-tool/WEB-INF/lib/log4j-1.2.14.jar
./webapps/profile2-tool/WEB-INF/lib/log4j-1.2.14.jar
./webapps/sakai-gradebook-tool/WEB-INF/lib/log4j-1.2.14.jar
./webapps/sakai-reset-pass/WEB-INF/lib/log4j-1.2.14.jar
./webapps/sakai-site-manage-group-section-role-helper/WEB-INF/lib/log4j-1.2.14.jar

This cannot possibly be what we want.  I ran into a problem where accountvalidator started before access and Sakai got confused badly and would not start. It seems as though we should change the poms in these elements not to include their own personal copy of log4j.

Or is there a reason we want things this way?
