As locked JARs on undeploy is a popular topic, I thought I would share a
recent discovery. If you read your log4j configuration file from a JAR,
the JAR will end up locked, preventing a clean undeploy.

Full details are here:

Mark,
is this specifically a log4j-linked problem, or does this affect any
other properties/configuration files loaded from JARs ?

It will affect any file loaded from a JAR via a URL where there isn't a
call to URLConnection.setUseCaches(false).

To this self-confessed dummy, this sounds as if, even though files loaded from JARs may not be so frequent, but given the thousands of Tomcat's out there, it ought to affect quite a few installations. Might it also be a reason why some Tomcats do not seem able to shutdown properly when told ?
(Don't spend time answering this if I'm talking nonsense.)
