Aborted 1.7.2 Release - Cleanup starting

Various issues discovered with javadoc generation.  Assuming a few things currently.

1) Spring / Tomcat builds have issues for duplicate class path items.
2) Shiro appeared to have issue due to invalid javadocs but fixes didn't seem to resolve issue.

This pull request is to bring code base current and note the aborted release plus shiro javadoc corrections.  Additionally, multi module build has been verified as it did push to central.  Issue was local thus not a release plugin issue.
