Description MackSix 2013-04-28 16:38:32 UTC 
Created attachment 133890 [details]
Example project to reproduce issue.

If we have this:

    Pair<Integer, Pair<? extends Pair<String, String>, ? extends Pair<String, String>>> pair7 
                = new Pair<Integer, Pair<BookAuthor, BookAuthor>>(789, 
                new Pair<>(new BookAuthor("\"Book1\"", "Author1"), 
                new BookAuthor("\"Book2\"", "Author2")));

NetBeans shows error badge with note that says:

Incompatible type
    required: Pair<Integer,? extends Pair<String,String>,? extends Pair<String,String>>>
    found: Pair<Integer,Pair<BookAuthor,BookAuthor>>

Then there is a refactoring options to:

   Chagee type of pair7 to Pair<Integer,Pair<BookAuthor,BookAuthor>>

When this is chosen, it produces:

   Pair<Integer, Pair<BookAuthor, BookAuthor>>> pair7
                = new Pair<Integer, Pair<BookAuthor, BookAuthor>>(789, 
                new Pair<>(new BookAuthor("\"Book1\"", "Author1"), 
                new BookAuthor("\"Book2\"", "Author2")));

Which is an error because there are 3 closing ">" instead of 2.

See attached project.

Honza, if you want to push it into release73, please do so today .
Comment 5 Jan Lahoda 2013-05-07 13:23:02 UTC 
After thinking about it, lets defer to next patch, if any, or to 7.4. Has been a problem for years, and I would like to get more confidence in the patch before backporting.
