Bug 80364 [Quick Assist] "Assign parameter to field" does not work for existing field
In this small example, there does not occur the quick-fix to "Assign parameter to new field": public class Foo { private final Bar bar; public Foo(Bar bar) { } } Even worse: when I remove the final from the variable declaration, invoking the quick-fix creates a new variable bar2 instead of reusing the existing one.
