Hum... There is some instability here. I don't know what combination of dynamic proxies/collection proxies is causing this bug. I've fixed using either proxy=true in the collections inside each bean...
Why? I really don't know. I'll need to compare each of the 12 collections
involved in this beans to know what's give the stack trace...
I'll need sometime to restart the app 132 times to know :(
Anyway, if someone could send me the rc5 implementation of the method, so I
can compare with actual, I'll appreciate.
Thanks in advantage.

This bug is driving me crazy... Someone could point me what changed from rc5
to 1.0 in this method (so I can at least fix locally)?
The problem is a M:N mapping using composite pk pointing the M bean, and 1
field pk pointing to the N bean.
The stack trace is:
java.lang.ArrayIndexOutOfBoundsException: 1
