Using JetBrains 64-bit Runtime as JRE/JDK on Windows
Hello,
I am interested using the JetBrains Runtime as my JRE and JDK with IDEA 2016.3. Now IDEA comes with the 32-bit JetBrains Runtime JRE but not JDK. I would like to use the 64-bit build. I downloaded jbsdk8u112b408.2_windows_x64.tar.gz from https://bintray.com/jetbrains/intellij-jdk/openjdk8-windows-x64#files/ which is the same version as the included 32-bit version with IDEA.
I extracted it and setup IDEA_SDK_64 to point to that location and ran idea64.exe and all works fine which is great. Programs compile and run just fine.
Now my questions
1. is using the JetBrains 64-bit Runtime (JRE/JDK) on Windows supported/recommended?
2. is there any problem using later releases of the JetBrains 64-bit Runtime such as jbsdk8u112b287.2_windows_x64.tar.gz?
3. is there anything else I should know about working with this setup? I like the idea of a portable JRE/JDK which Oracle does not support (although possible if you manually extract the installer contents as described at http://stackoverflow.com/a/6571736)
Many thanks!

1. It's supported and recommended if you want to use large heap sizes for IDEA. It's not recommended to use it as the target JDK for your own code in case it introduces any issues which will break your code (very unlikely, but I'd stick to the Oracle JDK).
2. You can try, they usually fix some problems, but can potentially introduce new issues. If you want to be on the safe side, use the same version that comes bundled with the latest IDEA release.
Thank you Serge :)
