Confused: IllegalStateException
Basics: Apache Tomcat/7.0.22 1.6.0_22-b04
I have a Grails app that I'm deploying to this Tomcat. During the
deployment, I see the following in catalina.out:
Nov 2, 2012 2:25:18 PM org.apache.catalina.startup.HostConfig deployWAR
INFO: Deploying web application archive Catalog##0025.war
log4j:WARN No appenders could be found for logger (net.bull.javamelody).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig
for more info.
Nov 2, 2012 2:25:41 PM org.apache.catalina.loader.WebappClassLoader loadClass
INFO: Illegal access: this web application instance has been stopped
already. Could not load com.mysql.jdbc.SQLError. 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
at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1564)

at java.lang.ref.Finalizer.access$100(Finalizer.java:14)
at java.lang.ref.Finalizer$FinalizerThread.run(Finalizer.java:160)
After this, the app seems to continue loading normally. I have tried
this on 2 Linux boxes (same Tomcat & JVM). I see this on both, but on
one of the boxes, the app behaves very strangely (causing an error I
haven't tracked down yet). On the other box, it runs fine.
What is this message trying to tell me? Is this a true indication of
an error? Or is it just a warning I can ignore safely?

e 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,"
I ended up restarting Tomcat, cleaning the app directory & rebuilding
the app. Worked fine after that.

Thought as much, thanks for confirming.

This would seem to indicate that an application which has been stopped (possibly because it has been undeployed) is executing code that would require the web application's class loader to load a class (specifically the com.mysql.jdbc.SQLError class). Since the application has already been stopped, the class loader associated with it is refusing to load the class.
Based on this, it would seem that you have the MySQL driver bundled with the application. You might want to try moving this to the shared class loader (i.e. the "lib" folder). I think that might clear up the message.
>>> Is this a true indication of an error?[1] Or is it just a warning I can ignore safely?[2]
The error message seems to answer these questions…
[1] - "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,"
[2] - "and has no functional impact."
Hope that helps.
Dan

I am using Tomcat's WAR upload and deploy (i.e., through manager app).

How are you deploying the application? What are the exact steps that you are taking?
