Hi,
FYI: I don't think I'd call this a crash. It is just an exception,
mysterious to you as it might be. A crash in Java land suggests an
abnormal and abrupt termination of the JVM, usually caused by a bug in
the JVM. I got most of the way though your message before I
understood what you were asking.
On to NSForward exception. Did you read the documentation for this
exception? That is a good place to start. Another good place to
look for help on these matters is the archive of this list and the
Omni archive:
http://www.omnigroup.com/search-bin/webobjects-dev?Search=NSForwardException
You can ask NSForward for the originalException() that it is
forwarding. That will likely provide more of a clue. Not explicitly
mentioned by the docs is that this is also used to wrap
java.lang.Error, a family of exceptions representing serious abnormal
conditions such as running out of memory, overflowing the stack, Bill
Gates buying a TiBook, and similar situations.
My guess is that you are getting either a OutOfMemory or StackOverflow
error due to a defect in your logic provoked by a certain pattern of data.

I'm having a hard time tracking down a crash in a report that I have.
On my 'dev' box (OS X) which I have project builder on I can compile
and run this application with out error. I have it pointed at the prod
database, I use the same usernames and logins, and it runs fine.
I then build a split build of this application, and copy the files to
our prod 'web' server. (OS X) and deploy the application. For all
users (save 1) there are no issues with this report. With the one user
the report crashes, with no stack trace. I get an NSForwardException.
(Error message below)
My assumption was there was an error in the data, that I had not dealt
with (i.e. a null is returned, and unhandled exception), but since it
runs in my dev, I can't determine what i have missed.
Has anyone seen anything like this that could point me in the right
direction?
Thanx
