web app demonstrating the issue

If a tag calls itself recursively, it doesn't work in Tomcat 5.5.30.  This has been observed on Linux, but (for whatever reasons) may not manifest on other operating systems.  I specifically reproduced the issue using 

java version "1.6.0_20" 
Java(TM) SE Runtime Environment (build 1.6.0_20-b02) 
Java HotSpot(TM) 64-Bit Server VM (build 16.3-b01, mixed mode) 

I'm attaching a simple war that renders (at the context root) a page with a recursive table structure on other versions of Tomcat (I tried 5.5.28 & 6.0.29), but not in 5.5.30.  Similar tag calls in our application have resulted in the following stack trace on this Tomcat version:
