Description

I placed a charger and the server crashed upon placement. I have the complete logfile, the except from that log file, and the crash report.

Environment

See log files below
crash-2016-11-18_03.39.28-server.txt
fml-server-3.txt
Logfile.txt

• Minecraft Version: 1.10.2
• AE2 Version: rv4 alpha-6
• Forge Version: 12.18.2.2125

And the same thing just happened when placing the inscriber. (note, everything loads back up fine when the server starts back up. Thankfully!)
Here are the logfiles from placing an inscriber:
crash-2016-11-18_03.55.02-server.txt
fml-server-latest.txt

Can you please reproduce it without any other mod? The code path is actually not possible with only AE2.

@yueh if you LinkedList.add(null) this could possibly be a thing or am i wrong? But i was not able to trace all possible sources now where a null could possibly be added

There are only 2 calls to it and both are guarded against null.

yeah i see it now, this one is very very odd :)

Updated the server to Forge 2147, plus updated

and the problem seems to have gone away. I spawned in a few other AE2 items and placed them and there weren't any issues that I could see.
