That is not a valid assumption.

Look at the next code snippet

Is there some way to pause before retrying the database transaction? If you
don't, then it seems to me that the processes that are banging into each other
are going to keep failing. I'd like to add a pause for a random amount of time
in the catch block.

Ah, thanks. So if I knew how many servers my cloud is made of then I should
use that number for my MAX_RETRIES. ;-)
I'm curious about how others are handling the exceptions. The
JDOCanRetryException is subclassed by other exceptions that don't seem like
things I'd want to retry, but perhaps
I think my try/catch is missing a catch at the end:
catch (final Throwable ex) {
exception = ex;
break; // fail
}

Excellent; thanks. I also took out the "uber catch" I was thinking I needed;
it was late at night and I was awash in catch blocks.
