Mike Drob commented on ACCUMULO-3611:
-------------------------------------
It's trying to do history expansion.
https://github.com/jline/jline2/blob/master/src/main/java/jline/console/ConsoleReader.java#L686
Should be possible to escape the exclamation. Maybe we can accept a flag to
disable expansion for the current session.

> I tried changing it back but it would not let me create a password with an
> exclamation mark in it, accumulo produces an exception saying the event was

> Might be a bug in JLine which we need to look into. We need to make sure that
