Doc Text:
An issue with specifying a JLine dependency resulted in the +Ctrl-C+ keyboard command not functioning in the console installer of JBoss EAP 6 on Microsoft Windows Server. In this release of JBoss EAP 6, JLine has been updated so that when +Ctrl-C+ is entered during a console installation on Microsoft Windows Server, the installer now quits as expected. Also note that the +Insert+ key is read as the same character as +Ctrl-C+, and will also quit the console installer if pressed.

I've looked into this, and found out a change in the jline dependency is needed to resolve this issue. After some testing I found out jline read the Insert button and Ctrl-C as the same character code on windows. Making a change in jline's ConsoleReader.java class will allow use to exit with Ctrl-C (but also if the Insert button if pressed)

If you would like to exit with a similar combination I have made some changes so that Ctrl-D will exit your program. The reason for this is because there is a bug where Ctrl-D will pass in a null value into our installer. Also the unix meaning of Ctrl-D means the end of any further text input.


While playing with jline I also got the tilde to expand the the full path of the user's home directory, both in windows and unix (https://bugzilla.redhat.com/show_bug.cgi?id=883419). Although on windows paths starting with C:\ seems like it still won't auto-complete(https://bugzilla.redhat.com/show_bug.cgi?id=1013972). If we end up being able to modify jline I may look into these more.

Let me know what actions to take if any. Thanks.

Hi Miles,
can you than look more into jline and try to modify it so we get the same behaviour for Ctlr+C and Insert as we have with 6.1.1 installer? 
Comment 3 Miles Tjandrawidjaja 2013-10-23 10:43:07 EDT

Jline has been updated so Ctrl+C will not exit the console installation on Windows. Modifications have also been made for places where jline is not used to enable Ctrl+C to exit from console installation on windows.

Correction to above comment.
Ctrl+C will 'now' exit the console installation on Windows.
Comment 5 Petr Kremensky 2013-11-01 10:25:13 EDT
Verified on EAP 6.2.0.ER7 installer.
Comment 7 Petr Kremensky 2013-11-13 02:54:30 EST
We may add the note about jline reading the Insert button and Ctrl-C as the same character code on windows -> exit the console installation. Someone may be confused by this.
