Thank you for the comments, Stack and Josh. It looks like the author agreed that they give us special permission to use Lanterna under Apache 2.0: https://github.com/mabe02/lanterna/issues/415
In this case, how to proceed? We need to make a note of this (maybe in http://hbase.apache.org/license.html)? Or we can just use the library without any notes? Sorry to bother you, but I'm not familiar with license things.
