Hello,
I've been a NhProf user for several years now. I'm currently helping
in a java application, and wanted to introduce HProf.
I started off simple:
HibernateProfiler.initialize();
When I launch HProf.exe, I only see SessionFactory Statistics, no
sessions, sqlstatements ...
When I stop Tomcat, I get these SEVERE warnings:

Fixed. Found another thread referencing the same problem. Just for
anyone encountering the same problem:
We changed our dependency from slf4j to slf4j-log4j
from our pom.xml:
...
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
<version>1.6.1</version>
</dependency>

That's the Ayende effect: asking a question correctly points you in
the direction of a solution.
The warnings when I close Tomcat remain however. When I remove
HibernateProfiler.initialize(); => no warnings.
Any hints?

Hm, thanks for catching those. We aren't really aiming at production deployment, but did you call the HibernateProfiler.shutdown() before closing? That should shut things down.

Nope. I'm going to try that, and I'll get back to you.
