    Preondition Violations
    Unmatched statement protocol.logout(); cannot be moved before or after the extracted code, because it throws exception(s) that should be caught by a try block that will be extracted

    Precondition Violations (3)
    Row Violation
    1Unmatched statement protocol.logout(); cannot be moved before or after the extracted code, because it throws exception(s) that should be caught by a try block that will be extracted
    2Unmatched statement new InfoViewerDialog(url); cannot be moved before or after the extracted code, because it throws exception(s) that should be caught by a try block that will be extracted
    3The refactoring of the clones is infeasible, because classes org.columba.mail.imap.IMAPServer and org.columba.core.gui.plugin.PluginManagerDialog do not have a common superclass
