ArrayIndexOutOfBoundsException - Hard to determine what is wrong

[Wayne Kidd]

When I use the same code on a much restricted set of objects, the error 
does not occur.  The proxy situation is that all Class descriptors have 
no proxy.  The Collections have proxy="true" and the references have 
proxy="false"  auto-retrieve on "true" for all relations.  There are no 
declared Interfaces.  It is entirely possible that the object retrieved 
could come back to itself through a series of relations

Accessor >---<Department  n:m  through a intermediate object (with 
meaningful attributes) called DepAccess
Accessor>---Role  m:1  An accessor has 1 Role

Each of these things has a number of other relationships which do not 
participate in this request (directly) but all Collections are 
autoretrieve and proxy true, while all references are autoretrieve with 
proxy false.  If I remove all collections and references except those in 
the particular code from the repository.xml , the code works.  If I 
leave all 100 tables in the repository.xml, it fails. 

Help.



Here is the error:
