According to Boomi support, the officially supported version is 1.8.0_66-b17. This is the version that Boomi uses on the Atom clouds and for testing.
I have some issues which might be JDK version related. Bottom line: when I install a new Atom on a Linux box, it does startup once, but after a config change, it refuses to start. Don't have any time now to share all the details now, but I've opened a support case for this. I'm currently using different versions for different customers, both open JDK and Oracle JDK, usually build 102, 111 or 112.
1.8.0_66-b17 is pretty old but I could give it a try. I prefer the Oracle JDK in that case. Which versions do you recommend?
