      The bug

      Worlds aren't deleted after dying in hardcore mode.

      How to reproduce

      1. Die in hardcore mode
      2. Click "Delete world"
        → This returns you instantly to the title screen
      3. Click "Singleplayer"
        → The world is still in the list

      Opening the world will bring you back to the death screen, and produce a long list of the same error, repeated many times, in the Game Output tab in the launcher:

      [06:05:34] [Client thread/FATAL]: Error executing task
      java.util.concurrent.ExecutionException: java.lang.NullPointerException
      	at java.util.concurrent.FutureTask.report(Unknown Source) ~[?:1.8.0_45]

      Caused by: java.lang.NullPointerException
      	at bcy.a(SourceFile:455) ~[1.8.7.jar:?]
      	at go.a(SourceFile:54) ~[1.8.7.jar:?]
      	at go.a(SourceFile:12) ~[1.8.7.jar:?]

      	at g.a(SourceFile:60) ~[1.8.7.jar:?]
      	... 3 more

      This may happen because the world still appears to be loaded, even after returning to the title screen. Clicking the Options button will show the hardcore world in the background.
      Also in the Game Output you can see that the server was not stopped:

      Game Output (15w47c)

      [22:38:14] [Client thread/FATAL]: Error executing task

      As you can see the "Delete" button does not cause the stopping of the server but instead the reopening of the world. Clicking the "Delete" button does not seem to do anything at all.

      The reason

      The following is based on decompiled version of Minecraft 1.8 using MCP. All method and class names are the names used in the decompiled version.

      The reason why this happens is very likely that the client thread tries to save the world after the client was kicked, while the server tries to delete it at the same time.
