Have you considered simply using CATALINA_BASE to run separate Tomcats?
That would likely be easier than writing an embedded Tomcat wrapper, etc.

Are you sure Tomcat is completely shut down when you perform the delete?
If not, Tomcat might have some in-memory notion of what's on the disk,
and get confused when the files suddenly disappear.

Have you tried undeploying the webapp and re-deploying? That should
cause Tomcat to clear it's own work directory for that webapp.
