B4J Question Using different Java versions for compile and runtime

[avalle]

Hi everyone, question from Java newbie here...

I am compiling a B4J server project with the current pre-packaged version of OpenJDK (14.0.1), but I have to run it on Ubuntu Linux 20.04 with a different version of the Java runtime (17.0.1).
I'm forced to use the runtime from OpenJDK 17 because it's already installed on the target machines and I'm not allowed to install other versions of Java.

Can this cause any problem to the execution of my application?
Should I compile with Java 17 as well?

@Erel are you planning to release a pre-packaged version of OpenJDK + OpenJFX 17 anytime soon?
If not, which Java packages should be installed on my dev computer to compile successfully from B4J?

Thanks
Andrea

Running Java 14 code on a Java 17 JVM shouldn't cause any problems.
(The only caveat is check for deprecated modules - example Java 9 has Nashorn - Java 17 does not)
