NullPointerException on server load

Hoping there's still someone listening here...

What I did:

Used Inductive Logistics advanced pipes extensively, connected to many things.

What happened:

Restarted the server one day and got a NullPointerException. Unable to work out exactly which connection causes the issue as I'm unable to load that area at all.

[15:04:41] [Server thread/ERROR] [net.minecraft.server.MinecraftServer]: Encountered an unexpected exception
java.lang.NullPointerException: null

This struck me as likely to be similar to a previous issue where sources were not ready to supply fluid in the first ticks after server startup.

Looking at the source, I see a number of null checks, but there's one case that might be the issue: you are iterating over the result of acc.getTankProperties() without checking it.

Sadly my Java-fu isn't strong enough to get the source compiling, so I can't test this theory. Just can't get InductiveLogistics to find CD4017BE_lib.

Used Versions:

  • Minecraft-1.12.2
  • InductiveLogistics-1.3.3
  • CD4017BE_lib-6.4.6
  • Forge-2838
  • Pack- SevTech Ages 3.1.2
