Re: inconsistent exception usage + question

Actually, I'm attempting to use the transaction's lease for the purpose 
you outlined below: to release resources.   The issue is that it's not 
just Jini resources that I need to release, so I'm looking for an 
orderly failure that I can intercept and react to.

I don't need to renew the lease; I want the timeout to occur.   But I 
need a method by which I can postmortem the failure of the transaction 
to verify that it was indeed the timeout (rather than, say, the 
transaction manager coming down or the transaction already being 
committed/aborted).
