    Expression server.dropConnection() is a method call throwing exception(s) that should be caught by a try block that will be extracted
    Expression protocol.logout() is a method call throwing exception(s) that should be caught by a try block that will be extracted
    Expression server.dropConnection() is a void method call, and thus it cannot be parameterized
    Expression protocol.logout() is a void method call, and thus it cannot be parameterized
    Type org.columba.mail.pop3.POP3Server of variable server does not match with type org.columba.ristretto.imap.IMAPProtocol of variable protocol
    • Make classes org.columba.mail.pop3.POP3Server and org.columba.ristretto.imap.IMAPProtocol extend a common superclass
