Sebastian, thanks for spending some time on it!

The error you get is different probably just because I am based on 
WMServlet and you are based on Standalone.

This is very strange though, because we know for a fact that other JARs are 
reloaded fine in Tomcat and Resin.

So there must be something specific to webmacro.jar that is different. It 
does not look like some strange classloader usage issue -within- WM code 
though, which was possible with my flavour of the problem, because yours is 
a class loading (rather than resource) problem.

The "touch" working without problem sounds to me like there might be some 
intelligence going on in the classloader, or because no code has actually 
changed it continues to work with the previous code on the previous 
classloader perhaps.

This is all speculation but that's all we have right now!

I'll see if I can see anything in the way the jar is built. I know, I must 
be crazy... but maybe its a problem with reloading zipped JARs vs unzipped 
jars for example.
