Get Java for your Mac Download Java for OS X directly from Oracle. Get the latest version If an app or webpage you want to use asks you to install Java software, you can download the current version of Java for OS X directly from Oracle's website. If the application is not present on your computer, Java Web Start automatically downloads all necessary files. Java Web Start will then cache the files on your computer, so the application is always ready to be relaunched any time you want - either from an icon on your desktop or from the browser link. Normally, this will be the “Downloads” folder, since this is where the downloaded Java Web Start files will be placed by default. From the drop-down in the upper right, select “Other” and browse to the Downloads folder. Once that folder is opened, click the Choose button, and the drop-down should now read “Downloads”. With macOS Catalina we are experiencing the following problem: opening Java Web Start applications behaves differently when application starts by double clicking on JNLP file and when it is started by double clicking on a shortcut installed on a desktop. The easiest way to download jDip is to click on the Web Start download below. If the Web Start link does not work, Java may not be installed. Windows users may download the version of jDip with the latest version of Java included. Users of Windows, Linux, and Solaris can get Java here.

This fixed the issue for me:
sudo /usr/libexec/PlistBuddy -c 'Delete :JavaWebComponentVersionMinimum' /System/Library/CoreServices/CoreTypes.bundle/Contents/Resources/XProtect.meta. plist
In the comments to the linked article someone suggests to comment out the node in stead of deleting it. Probably safer (it's explained further down how to do that). Anyway I already spent to much time on this nonsense, deleted it and it worked, so I'm happy.

After upgrading to a newer version of Mac OS X (Yosemite 10.10 and El Capitan 10.11) or macOS (Sierra 10.12 and High Sierra 10.13), you may end up getting an annoying new pop-up message whenever you start your computer. It says, “To use the java command-line tool, you need to install a JDK.” It asks you to click “More Info” and visit the JDK (Java Developer Kit) download website.
The reason you’re receiving this message is due to the removal of Java support in newer versions of OS X for security reasons. Older software such as Adobe Photoshop and Illustrator requires legacy Java support. Without a compatible Java command-line tool for these software, you’ll get this pop-up every time you turn on your Mac computer.
Install Java On Mac
When you visit the download website to update Java, you find that the issue isn’t resolved! You’re still getting the same pop-up. This isn’t a complicated issue to fix, but it is an indirect one. The problem is that you’re not being routed to the correct download website when you click “More Info.”
Apple could have remedied this issue by programming the “More Info” button to direct you to the right fix. Here are the steps you can take to finally rid yourself of this pop-up:
