Major Spigot/Craftbukkit will fail to populate a large number of chunks when using a custom world generator. This happens mostly when the world is being generated for the first time at startup.
at line 283 of net.minecraft.server.ChunkProviderServer there is a try/finally block around the population loop. This seems to fail quite often at initial load of the world, I'm guessing probably a race condition somewhere causing a ConcurrentModificationException causing populator.populate to never be called, however, the ChunkPopulateEvent IS called.
net.minecraft.server.ChunkProviderServer.java
| try { 282| for (BlockPopulator populator : world.getPopulators()) 283| populator.populate(world, random, chunk.bukkitChunk); | } | finally { 286| this.world.populating = false; | }
This can be worked around by listening to the ChunkPopulateEvent and checking if it is called without first calling the populator.populate method. If it is, you can recall the populate method.
As you can see, it fails to populate a lot of chunks
