The detailed

Answer 1

I hit the same issue on my mac OSx El Capitan. I tried updating the java paths/envs used by R using "R CMD javareconf" with no effects.

Finally, I saw that when I ran "R CMD javareconf" my Java library path: in the output was empty. By digging up further I figured out that my JAVA_HOME was not set correctly as pointed here https://stackoverflow.com/a/3311983 . I had to add an extra /jre in the JAVA_HOME path.
