Setting the terminal to a POSIXTerminal in the ShellImpl constructor did the trick. I also
had to update the Aesh dependency to 0.51-SNAPSHOT on the shell add-on to include a
necessary fix in POSIXTerminal to make it all work.
So I guess Stale needs to do a new Aesh release as well before Forge 2.2.1.Final can be
released with all the stuff needed for JBT 4.2.0.Beta1.
See you tomorrow!
