If you have the following two errors building your Java projects using Eclipse,

• Unsafe cannot be resolved to a type
• The import sun.misc.Unsafe cannot be resolved

Then, this turns out to be the fix for me.

Navigate to the project and Select Project – Preferences – Java Compiler – Enable project specific settings – Compiler compliance level = 11 – Use default compliance settings (Ticked)

Apply and Close – then do a full clean rebuild, which will make the errors go away!
