      Clarification note

      This bug seems to be caused by a JVM bug:

      We've identified the big 1.13-pre4 crash as a bug in Java itself! We have a fix lined up, but it's always exciting to be reminded that the JRE isn't infallible.

      Source

      It looks like at least Java 1.8.0_51 and newer versions should solve this issue (used by default by the launcher).

      See MC-138125 if you experience this bug with an up to date Java version.

      The bug

      When creating a new world on 1.13-pre4, the first time I loaded up a new world, the game hung up on the "loading world" screen. The second time, it loaded 25% of the spawn area. Closing the game and loading the world progresses the "preparing the spawn area" screen between zero and four percent each time. After ten times attempting to load a new world, I'm at 36%.
