Glen Mazza commented on DERBY-1447:
-----------------------------------

Incidentally, Apache Karaf's command line shell has this functionality, both 
up/down arrow and history--being not only Apache-licensed but Apache-owned 
code, there should be no legal problem with effectively taking it as-is and 
placing it in ij.  However, while I like the up/down arrow functionality to 
repeat and/or edit recently made SQL statements, keeping a history file of 
commands which Karaf does would probably be ill-advisable, as sometimes 
information being inserted via SELECT/UPDATE, etc., statements can be 
sensitive/private and it wouldn't be good to keep that data in an unsecured 
file.
