Reuploaded a new version that fixes a bug present in -v3 for empty chunk sections. Especially in the nether this caused some funky lighting, because the chunk section directly above lava is all air (and thus empty'd out). it caused a lot of broken lighting. This has been fixed now.

This version fixes problems with the Java garbage collector causing the server to run out of memory when fixing entire worlds (or just a lot of chunks). It now explicitly garbage collects after every big step to prevent this.

Update BKCommonLib and Light Cleaner will support all these versions:

• Spigot 1.8.8
• Spigot 1.9
• Spigot 1.9.2
• Spigot 1.9.4
• Spigot 1.10.2
• Spigot 1.11.2
• Spigot 1.12
