This is how I solved in Gnome -
1 - create file /usr/share/applications/java.desktop
In it, paste the below. It may not be perfect, I just wrote this as I went -
[Desktop Entry]
Name=OpenJDK
Comment=Java Application Launcher
Exec=/usr/bin/java -jar %f
Icon=java
Terminal=false
Type=Application
NoDisplay=true
Categories=Utility
MimeType=application/x-java-archive;
2 - In Files/Nautilus, right click a jar and click properties. On the ‘open with’ tab, click Reset at the bottom - I had to do this to get OpenJDK to then show up. Then select OpenJDK, and click Set as Default.

Failed to mount '/dev/sdb1': Input/output errorNTFS is either inconsistent, or there is a hardware fault, or it's a
SoftRAID/FakeRAID hardware. In the first case run chkdsk /f on Windows
then reboot into Windows twice. The usage of the /f parameter is very
important! If the device is a SoftRAID/FakeRAID then first activate
it and mount a different device under the /dev/mapper/ directory, (e.g.
/dev/mapper/nvidia_eahaabcc1). Please see the 'dmraid' documentation
for more details.
