      Description

      This has happened to me several times since this morning. When exploring a map in Creative, within only a few minutes, the chunks stop loading/appearing and only the sky is visible overhead as well as underneath. The game then crashes, refusing to even save and quit (freezes on the game menu screen). I have to force quit the application to get out. A precursor to this is that I seem to jump backwards several times while flying, as though the game was trying to pull me backwards to a previous location several blocks behind me and re-start the loading process from there.

      The error when the game crashes reads as "Java(TM) Platform SE binary is not responding".


      How to reproduce this issue with some reliability:

      1. Start Minecraft with 2048M as the maximum RAM allocation.
      2. Create a new Default world in creative mode.
      3. Set view distance to 12.
      4. Build the chunkloader machine described here: https://www.reddit.com/r/Minecraft/comments/8qfpk1/a_machine_for_pregenerating_chunks_in_vanilla/
      5. For the chunkloader, start generating chunks at x=-4096, z=-4096 (command block 5), with 33 items in the two hoppers B and C. (Also swap the commands in command blocks 5 and 6, and add a 20-second delay with a line of repeaters before the setblock command that starts the machine).
      6. For command blocks 1 and 2, have a relative jump of 256 blocks instead of 192.
      7. Start the machine by pressing the button.
      8. At some point, the symptoms described in this bug report and/or MC-129492 will occur and chunks will stop loading. This is when the server thread has crashed by running out of heap space.
