Subject log4j SEVERE ThreadDeath in Tomcat 5.0.25
Date Thu, 05 Aug 2004 09:31:43 GMT
We are experiencing Tomcat failure as soon as the following exception gets thrown;

SEVERE: Exception invoking periodic operation: 
java.lang.ThreadDeath
	at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1229)

This exception we have discovered mostly occurs after a developer compiles classes to Tomcat
which makes Tomcat restart the context. Mostly, because sometimes it is fine. We cannot establish
a concrete pattern of behaviour except that some compiles of any class type that make TC reload
the webapp cause this unercoverable error.

This has happened with log4j1.2.8 and 1.3alpha0

Cheers, ADC
