Hello

I see this error in catalina.out but I don't understand what it means:

016-10-04 23:09:11,960 [Timer-3] INFO
org.apache.catalina.loader.WebappClassLoader- Illegal access: this web
application instance has been stopped already. Could not load
com.novell.idm.attestation.persist.AttestationRequ est. 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.
java.lang.IllegalStateException
