Holding ALT throws the same exception also.

I still cannot reproduce this. Could you please "set VERBOSE on" and post the full stack-trace?

Also, as an attempt to clear this up, could you try deleting your ~/.forge directory?

Thanks,
Lincoln

Confirmed it is a Jline bug from the version Forge is running.
Tested with an example downloaded on http://jline.sourceforge.net and the error did not occur on latest available version (1.0).

Any chance you could figure out what the difference is? I am unable to reproduce this issue. We have also now forked JLine into Forge itself, so we can directly fix any issue.
