Getting "[INFO] Unable to bind key for unsupported operation: backward-delete-word" when using ruby-debug with jruby 1.7.0

I get the following output after upgrading to jruby 1.7.0 and using ruby-debug:

[INFO] Unable to bind key for unsupported operation: backward-delete-word
[INFO] Unable to bind key for unsupported operation: backward-delete-word
[INFO] Unable to bind key for unsupported operation: down-history
[INFO] Unable to bind key for unsupported operation: up-history
[INFO] Unable to bind key for unsupported operation: up-history
[INFO] Unable to bind key for unsupported operation: down-history
[INFO] Unable to bind key for unsupported operation: up-history
[INFO] Unable to bind key for unsupported operation: down-history
[INFO] Unable to bind key for unsupported operation: up-history
[INFO] Unable to bind key for unsupported operation: down-history
[INFO] Unable to bind key for unsupported operation: up-history
[INFO] Unable to bind key for unsupported operation: down-history
(rdb:1)

And the debugger doesn't respond and I can only do <CTRL>-Z to exit and kill the process. A google search at present for any of those lines turns up zero results at present, so not sure at all where to look.

I have the exact same problem like that and stumbled upon a workaround. It might work for you too.

When you are prompted with that, press "v" and enter and you are in debugger mode!
