Hi,

I'd like to follow up on
http://www.mail-archive.com/tomcat-user@(protected).

I just setup an instance of TC 4.1.27, and applied the hotfix (GNU tar,
tar -xvzf 4.1.27-hotfix-22096.tar.gz). Verified that the hotfix was in
place.

Then, with the default setup & webapps completely unmodified, I was
fooling around with logging/debug options in the administrator to see
what kind of output various options produced. When I set loader
properties debug level = 9 for the examples context (which has
reloadable = true) I see the following in catalina.out:

First, a detailed error message (see below), then repeated instances of
the message:

WebappClassLoader:   Failed tracking modifications of '/WEB-INF/lib'
WebappClassLoader: modified()

That doesn't sound good to me.

As an aside, I've been using 4.1.24 for a while, and just tried setting
reloadable = true in one of my own applications for the first time a few
days ago; it doesn't seem to work. I'll bump up the logging and see if
4.1.24 produces similar messages, I guess.

----- detailed error message from catalina.out -----------
