[Building Sakai] Roster + cglib issue

[carl.hall at gatech.edu]

We found that sitestats had the cglib jar in WEB-INF/lib of the webapp and this jar is in shared/lib. We removed it from sitestats webapp lib and things look good now.

Thanks for the info. We'll try upgrading to a later version (most likely the version noted in the JIRA) and report back the findings.

Carl, 

could this be related to: 
http://jira.sakaiproject.org/browse/KNL-139 

Reported by Ray .... may be worth trying an upgrade of cglib

We only see this happen on 1 machine but I thought I'd ask around about it. It does kill the startup since the Spring bean fails to init. This is with Sakai 2.5.x 

When starting up Tomcat, we get the exception below. I've tried copying the cglib jar to the roster component lib (still fails) and removing the transaction proxy from the Spring bean (success!). Any thoughts or suggestions? 

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.sakaiproject.api.app.roster.RosterManager' defined in file [/opt/sakai/tomcat/components/sakai-roster-components/WEB-INF/components.xml]: Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: interface net.sf.cglib.proxy.Factory is not visible from class loader
