I on macOS 10.13.3 and I just update to java 10 and when I've tried to update R to it I just realize that I get two different outputs if I run R CMD javareconf with or without sudo. If I run with sudo it sticks to Java 9, but if I run without sudo it configures java 10.
Without sudo:
$ R CMD javareconf

Done.
The end result of this is: without sudo and in consequence with java 10, rJava doesn't build. With sudo and java 9, rJava build normally.
Does anyone know what is going on?
PS1/ I have set $JAVA_HOME to JAVA_HOME="$(/usr/libexec/java_home)" in my zsh and bash profile.
PS2/ just for the sake of having all the info in one place... when building rJava with Java 10 I get the following error:
warning: [options] bootstrap class path not set in conjunction with -source 6
warning: [options] source value 6 is obsolete and will be removed in a future release
warning: [options] target value 1.6 is obsolete and will be removed in a future release

I've checked and there isn't a javah on /Library/Java/JavaVirtualMachines/jdk-10.jdk/Contents/Home/bin/javah as in Java 9.
As it was discussed on the R-SIG-mac list the problem is solved if you update to the last dev version of rJava.
