finish. This is very likely to create a memory leak. You can control the time 
allowed for requests to finish by using the unloadDelay attribute of the 
standard Context implementation.

INFO: Illegal access: this web application instance has been stopped already.  
Could not load com.manuals.common.utility.Log.  The eventual following stack 
trace is caused by an error thrown for debugging purposes as well as to attempt 
to terminate the thread which caused the illegal access, and has no functional 
impact.
