To whom it may concern,

I'm confused to pinpoint where the cause occured. I have started my web app successfully but when I'm about to invoke my method which creates a task in the jbpm,
this exception appears:



Sep 7, 2012 6:07:25 PM org.apache.catalina.loader.WebappClassLoader loadClass
INFO: Illegal access: this web application instance has been stopped already.  Could not load org.jbpm.task.event.TaskCompletedEvent.  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.
