I have begun a migration from 5.5 to 6. Yes I know 6 is EOL but the migration 
from 5.5 to 6 has some more documentation compared to 5.5 to the latest version.

I followed the standard migration of libs and classes from /common /shared etc 
to the new /lin directory for 6..

The server engine runs and I can see the examples web pages come up.

When I migrated my production webapps to the 6.0 instance however I get the 
following error.

HTTP Status 500 - java.lang.LinkageError: loader constraint violation: when 
resolving interface method 
 the class loader (instance of org/apache/jasper/servlet/JasperLoader) of the 
current class, org/apache/jsp/index_jsp, and the class loader (instance of 
org/apache/catalina/loader/StandardClassLoader) for resolved class, 
javax/servlet/jsp/JspApplicationContext, have different Class objects for the 
type javax/el/ExpressionFactory used in the signature

Any insight on this is welcomed..

I notice in that my app has its own lib directory, does this means that there 
is a conflict with the lib files from the base directory ?
