What is the JetBrains version of products with JBR for and why is this version not available now?

Question

jetbrains

I noticed that most JetBrains IDEs up to and including 2019 for each OS had a version with JBR embedded.



I googled and found only this information about JBR - https://confluence.jetbrains.com/display/JBR/JetBr...

As I understand it, JBR is a slightly modified OpenJDK, which, in turn, is a set of open source libraries, utilities, packages and other components written in Java.

Actually questions:
1. How does the version "with bundled JBR" differ from the version "without bundled JBR" and from the version without any suffixes?
2. Why is there a version with JBR for the latest versions of JetBrains IDE (2020.x) only for Linux?

It's just that in my understanding, where "with bundled JBR" is not written, it means that in this version there are no additional components from OpenJDK, which, probably, will help in development.

PS
Yes, I'm not mistaken, I write JetBrains IDE (and not IDEA), because I mean all independent products (not plugins) for development.

Answer 1

1. weight. and nishtyaks.
2. perhaps because there are NO versions for other systems without JBR. at least under macos they come with jbr.

Answer 2

• The version that just says Linux comes with the latest 11 JBR, i.e. read as Linux with bundled JBR 11.
  
• The version that says Linux with bundled JBR 8 was delivered earlier and support has ceased in newer versions.
  
• The version without JBR assumes that you will build the required version yourself or will run it not with JBR, but for example with OpenJDK.
  

Regarding the second question: there is no support for using other versions besides JBR 8 and 11. New versions always have JBR 11 by default. In fact, you have the ability to run different versions of JBR, it is written in detail here.
