Hi Mark, With regard to using Tomcat in production, that was meant sarcastically - the team has done a nice job on later Tomcat 6 and Tomcat 7 32/64-bit installations - including Windows Service support, etc. - nice work.
With regard to using YourKit, I have a licensed copy, but must be missing something - where can I look to see what is holding a reference to the JAR? I've used it for memory analysis and CPU profiling - primarily, but I'm not sure where to look for JAR references.

If that were the case, the Tomcat devs wouldn't have put the investment they have into the Windows installer in recent months (auto detection of 32 or 64 bit JRE, greater control over ports, multiple service installs of the same version, ...) > With regard to finding a solution, I'll try the antiJarLocking > setting, but I don't have any problem with any other JARS, so I don't > hold out much hope for this fixing my problem.

You need to understand the root cause. I'd recommend getting a profiler (I use YourKit since they give free copies to Tomcat committers) and finding out exactly what is holding references to those JARs. Once you know that the next questions are 1. What creates those references and 2. How to get rid of them.
