[jira] Commented: (SMX4KNL-137) GShell makes a very loud beep when hitting backspace once too often on Windows

["Jamie Goodyear (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/activemq/browse/SMX4KNL-137?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=49023#action_49023 ] 

Jamie Goodyear commented on SMX4KNL-137:
----------------------------------------

The only references to the beep command is held within the jline console, specifically in Jline CandidateListCompletionHandler.java [1] and ConsoleReader.java [2].

My guess would be in ConsoleReader#readLine that the series of backspaces on Windows may cause an non-handled signal character to be processed hence causing the final default clause to be processed (if unsuccessful identification, then beep).

> When using the SMX 4 Kernel GShell console, if you hit backspace once too often on Windows, you get a really loud beep. I guess this is to indicate that there is no character to delete any more, but I guess the 'normal' behaviour of not doing anything would be good enough too.
> On my DELL laptop the beep is so loud (even if I have my windows sound volume switched off) that it nearly knocks me off my chair.
