I'm a new user in RePast learning to run the mesoFON model. I get this error message. What is the problem?

I'm using Eclipse IDE 2018-09.

It appears that there is an issue with a mesoFOM specific-method call. I'd suggest reaching out to the mesoFOM model developers directly to see if they can help.
