Mike Drob commented on HBASE-16196:
-----------------------------------
How about something like this for the release note:
{quote}
The bundled JRuby 1.6.8 has been updated to version 9.1.9.0. The represents a
change from Ruby 1.8 to Ruby 2.x which may introduce non-compatible language
changes for user scripts.
This JRuby version update required an update to joni-2.1.11 and
jcodings-1.0.18, used for regular expression matching, as well as several
transitive dependency updates that should not be user-visible.

> Update jruby to a newer version.

> Ruby 1.8.7 is no longer maintained.
> The TTY library in the old jruby is bad. The newer one is less bad.
> Since this is only a dependency on the hbase-shell module and not on
> hbase-client or hbase-server this should be a pretty simple thing that
> doesn't have any backwards compat issues.
