Example Java file with type errors which are not displayed by the NetBeans Java editor

See the attached Java file. It has type errors in both calls to someFunc, but the NetBeans Java editor fails to display the errors on the correct lines in the code editor (I expect wavy red lines and an icon in the line number gutter). The error icon badge is shown on the overall file's icon in the Projects side pane, though.

I believe this behavior is new for NetBeans 8.2. It would be very nice if it could be fixed--these kinds of type errors are very common during refactoring (e.g. when changing the argument of a function from a List to a Map), and the ability to see the errors highlighted in the editor is invaluable.

This bug is still present in NetBeans 8.2 Patch 2, with both the user dir and cache dir removed prior to running the IDE. The problem appears both in Maven and Ant projects, created freshly from scratch.
