THE PROBLEM is in the shortcut of Talend, no matter what you have done the shortcut has a field named 'Target' which has a value something like this in my case
"D:\Program Files (x86)\TOS_DI-8.0.1\studio\TOS_DI-win-x86_64.exe" -vm"C:\Program Files\ Java\jdk-11\bin"
As you can see it's a command settled the first time you installed Talend so if you need to change the version of JDK, change this path here also for the new JDK.
Note: Press Alt+Double click to see the shortcut parameters.
