Summary: Random error on finder method
Initial Comment:
I have a finder method and the executed SQL finds
ALWAYS one row. Strangely the finder method randomly
fails. I guess that the entity cache must be in some
kind of inconsistent state.That happens
when the server is under load. I could not think of
any workaround. Is it
possible that one entity in the entity cache is
corrupted because of some
weak references to its fields? Attached a TRACE level log.
