I am baffled that this over 6-year-old bug, which has a solution in the comments by G4me4u posted almost a year ago, has still not been fixed. This has high priority too and hasn't even assigned to a Mojang employee.
This bug is 7th in the list of java bugs when searching for open+reopened issues that are unassigned and have important+very important priority levels. And only 4 of those bugs, 2nd through 5th on the list, are older than this bug.
Again, this bug has a detailed solution with an explanation the comments, that is almost a year old, by G4me4u, and still hasn't been fixed.
