Simon,
Java is still one of the most popular languages out there, in
particular in large organizations. See e.g.
https://www.tiobe.com/tiobe-index/ . However, there has been a lot of
confusion because of Oracle's licencing change in 2019. But the good
news is, there are more alternatives than ever. See e.g.
https://labs.consol.de/development/2019/02/05/oracle-license-is-the-free-lunch-over.html
. And also Oracle has a very interesting new VM significantly
improving startup time, the community edition is under GPL-2. See
https://www.graalvm.org/ .
Cheers,
Adrian

> you could argue that Java is dead since Oracle effectively killed it by
removing all public downloads, but if you manage to get hold of a Java
installation then it works just fine with R. To my best knowledge there has
never been an issue if you installed rJava from source. macOS Catalina has made
binary distributions impossible due to additional restrictions on run-time, but
even that has been how solved with the release of rJava 0.9-12, so please make
sure you use the latest rJava. In most cases that I have seen issues were caused
by incorrect configuration (setting JAVA_HOME incorrectly [do NOT set it unless
you know what you're doing!], not installing Java for the same architecture
as R etc.). If you have any issues feel free to report them. rJava 0.9-12 has
quite a few changes that try to detect user errors better and report them so I
strongly suggest users to upgrade.

Windows. Travis CI builds "https://github.com/sbgraves237/Ecfun" just
fine.
