with Wrigley's Doublemint gum. In my case we're halving it at minimum.
I added mappedBy to my @Persistent annotations and now things are getting into
the Set twice. Very strange. I can't figure out what I'm doing wrong.
In the following setup() I'm adding 3 WaitlistEntry objects but the Set ends
with 6. The number of persisted WaitlistEntry objects is correctly 3.
Here are the relevant (I hope) bits of the usual suspects and a pretty printed
version of the dump of waitlistEntries that shows the duplicates.
The remaining sane parts of my brain thank you for your help.
