------------------------------------
Assignee: Ivo Ladage - van Doorn (was: Bram de Kruijff)

resulting chain invoked will just caontain the 50 filter relevant to the
tenant.

> I created a small performance tests which:
> - registers a single servlet
> - registers 50 filters and 50 tenants
> - fires 2000 GET requests to the servlet (synchronously in a single thread)
> When doing this, this always results in a StackOverflowError in the
> dispatcher:
> INFO: Added tenant tenant_50 in 1026 ms [pax-exam-probe]
> INFO: Running single performance test with 50 filters and 50 tenants.
