After the 4.26 production release of JMRI (which should happen very soon since it's now at 4.25.8) the developers will require you to upgrade Java to version 11. Azul Software's JRE is one of the recommended upgrade packages. This is based on the OpenJDK software and includes choices for both a JDK (software development kit) and a JRE (runtime environment). The vast majority of users will only need the JRE.
It is available on the Azul downloads page. You can select Java Version, Operating System, Architecture and Package to install . An example is shown in Fig 1. The developers also recommend that you do not install a version higher than v11 since JMRI has not been tested with those versions. Windows users should select the "JRE" and the ".msi" package. This is the auto-installer.

The author has had this Java version installed for some time now and has encountered no problems. It also appears to be slightly faster than the Oracle version.
If you have an idea for a blog post here, let me know. If I can comment on it, I will or I'll see if someone else can and post it.
Why a development kit and not a RE?
ReplyDeleteEither the JDK or the JRE will work. I was a java developer for over 20 years. If you do not plan to develop anything download the JRE. The JDK will just give you a lot of stuff you'll probably never use.
