question: public void init ( ) { StringBuilder buf = new StringBuilder ( ) ; String command = String . format ( ImageServerDialogProperties . getString ( "cmd.promptChange" ) , PROMPT ) ; try { sendWaitFor ( command , defaultTimeout , prompts , buf ) ; } catch ( NetworkDeviceControllerException e ) { log . error ( "timeout when trying to connect to image server: {}" , e . getMessage ( ) ) ; log . info ( "let's retry" ) ; sendWaitFor ( command , defaultTimeout / 2 , prompts , buf ) ; log . info ( "retry worked" ) ; } command = String . format ( ImageServerDialogProperties . getString ( "cmd.termLength" ) , 1000 ) ; sendWaitFor ( command , defaultTimeout , prompts , buf ) ; }
