Infinite loop in Glassfish exception logging

When Glassfish catches a ServletException, it calls getRootCause recursively on each successive unwrapped, nested exception by reflection.  This is fine for wrapped ServletException and JspException, which have well-defined semantics for this method, but creates a big problem if you have an application-defined exception that happens to use the same "getRootCause" name with different semantics.

So I created a Glassfish bug report:
http://java.net/jira/browse/GLASSFISH-17390

Related original bug in Tomcat, since fixed:
