Hi
I periodically receive this exception in tomcat 6.0 with hibernate 3.3 and
c3p0 as connection pooling library...
can you point me to docs to further investigate the problem?
thanx
the stack trace is :
6-lug-2009 9.08.31 org.apache.catalina.loader.WebappClassLoader loadClass
INFO: Illegal access: this web application instance has been stopped
already. Could not load
com.mchange.v2.resourcepool.BasicResourcePool$1DestroyResourceTask. 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.
