Created attachment 275501 [details]
error shown here

This is like 483847, but here with a non-parametrized type, just String.

It shows incorrect return type.
The classes are in different packages.
Both classes are with @NonNullByDefault in the package-info.java

Comment 3 Frank Benoit CLA 2018-08-23 06:09:18 EDT 
The method getSimpleTitleName() is only defined in the 2 classes shown, the other classes/interfaces don't have it.
Comment 4 Stephan Herrmann CLA 2019-05-05 05:56:55 EDT 
Why move this bug to JDT/UI? The UI doesn't compute errors, it's the compiler in JDT/Core which does.

As usual: we'll need a reproducing example for investigation.

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet.

If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.
