If there is an insert() call in
org.tass.utils.ExpertSystemManager.java in line 156 then *this* is
where the insert occurs, not the insert() in the rule.
Where is org.tass.utils coming from?
It's still a mystery to me how it's possible to have a stack trace
element from NamedEntryPoint.java line 48 - there's no code in this
line.

it is the stack trace complete of this exception. Now I added some other
log lines.
If you mean other thing, please let me know.

through entry point. Is it possible that the error is related to this
insert operation?
Thank you and kindly regards!
