Today I accepted the Oracle offer to update my installation of Java on my High Sierra machine to their version 10.0.2 (build 10.0.2-13  ( from their build 10.0.2-10 ) and after 

user$ sudo R CMD javareconf 

... rJava 0.9-10 loads without complaint.

I tried installing micro plot from binary without error, but when I try to load the rJava library I was getting an error with the old Java version 151, so I accepted the Oracle offer of installing version 171 downloaded from the Java website, but I'm also seeing:
