I have found that many of the java components (.jar) files found in the Tomcat/lib folder are outdated. 20+ components.
One example, upgrading to MySQL to 5.6 AwareIM still communicates with it through buggy version of Connector/J JDBC driver which is a few years old.
Anyway, I thought I would share the list of the components I have replaced. So far so good.
Instead of changing the AwareIM/bin/awareim.conf, I've renamed the latest files and simply replaced the old ones.
AS OF 22 MAR 2014
Always keep backup of original files.
Replacing these files showed no server/tomcat startup errors in the log.
Cheers
