    Description copied from class: SSessionJdbc
    
    Main method for closing a session.
    
    Closes the JDBC connection and then calls detachWithoutClosing to detach the SimpleORM connection from the current thread. Should usually be put in a finally clause. No error if already detached or closed so safe in finally clauses.
    
    Specified by:
    
    close in interface java.lang.AutoCloseable
