Description Maxim Valyanskiy 2011-02-24 08:47:47 UTC 
Embedded Tomcat sometimes throws this exception when calling destroy() method:

java.lang.IllegalArgumentException: null source
	at java.util.EventObject.<init>(EventObject.java:56)
	at javax.management.Notification.<init>(Notification.java:184)
	at org.apache.catalina.core.StandardContext.destroyInternal(StandardContext.java:5433)
	at org.apache.catalina.util.LifecycleBase.destroy(LifecycleBase.java:285)

	at org.apache.catalina.util.LifecycleBase.destroy(LifecycleBase.java:285)
	at org.apache.catalina.startup.Tomcat.destroy(Tomcat.java:323)
	at su.msk.jet.nioproxy.rule.config.EmbeddedWebserver.stop(EmbeddedWebserver.java:26)

I think that StandardContext.destroyInternal() misses check that this.getObjectName()!=null

Thanks for the report. This has been fixed in 7.0.x and will be included in 7.0.9 onwards.

To avoid it in the meantime, ensure that the embedded Tomcat instance is started before you destroy it.
