Using a SessionCustomizer you can disable the connection reconnection.

package acme;
import  org.eclipse.persistence.internal.sessions.factories.SessionCustomizer;
import org.eclipse.persistence.sessions.Session;
import org.eclipse.persistence.sessions.DatabaseLogin;

public class EmployeeSessionCustomizer implements SessionCustomizer {

    public void customize(Sesssion session) {
        DatabaseLogin login = (DatabaseLogin)session.getDatasourceLogin();
        login.setConnectionHealthValidationOnError(false);
    }
}

This customizer can be set through a persistence unit property
