Reposting this (https://forum.unity.com/threads/please-download-embed-jdk-shared-in-unity-hub-folder.639241/) in the right forum. The issue still exists in Unity 2018.4. Whenever I perform a (minor) version upgrade, the Editor is still configured to use embedded JDK from the previous Unity version. This on its own could cause severe issues. However I usually delete the old Unity version straight away. Now this path becomes invalid, so I have to go to the settings menu and reset the embedded JDK path. This is not only annoying but I imagine also totally confusing for beginners (finding out what the errors mean). Please move the embedded JDK to a shared folder, such as the Unity Hub or the Java install directory.
