   I must admit that I'm getting very bored of PRs that apply these limits.
   POI is over 20 years old and has a lot of code. It was not originally 
written with security in mind. It is a free convenience library.
   This new code - all it does is switch from one type of exception to a 
different type of exception. So unprotected code might throw an Array Index 
exception or even OutOfMemoryException. Parse enough documents in parallel and 
you can still get OutOfMemoryExceptions.
   https://poi.apache.org/security.html warns that you should never parse 
untrusted documents with POI.
   We are introducing new problems with this code.
   The limits might be too low for some reasonable files. We now have dozens of 
different limits and the exceptions raised don't tell you what method to use to 
raise the limit.
   Even if we add some new tests, we are not getting 100% test coverage or even 
close to that number.
   
   I'm thinking of raising a general discussion among the POI volunteers about 
just giving up on this sort of work.
