[R-sig-Debian] rJava Broken on Linux + R 3.4

[J C Nash]

For those going to UseR! in Brussels, maybe a short meeting over coffee
to make some notes about the issues. I know I've had troubles before with
rJava over the years, and I won't pretend to be much more than a recipe
follower. However, if it's possible to have a few notes on "where to
look" for diagnostics and fixes, or even explaining what is going wrong,
I'll be happy to write them up and post somewhere. I've been doing such
short how-to items on our oclug.on.ca wiki for other software, and feedback
has been positive.

Best, JN
