[Addon Mod] java.lang.Nullpointer on startup [SOLVED]


I'm rewriting OC-Minecarts for 1.10.2. But the Carts won't boot. If I insert no BIOS it works as intended and tells me, that I have to insert a BIOS EEPROM, same if I insert a BIOS but no OpenOS, but if I insert a OpenOS disk and power the computer cart up. The Startup routine crashes with "Unrecoverable Error  java.lang.NullPointerException"


I don't know where this is coming from. The log doesn't tell me anything, even if I enable "logCallbackErrors" (and also some other options in debug category). Debugging with breakpoints also didn't help.

Forcing LuaJ it printed "machine:1447: machine:631: java.lang.NullPointerException stacktrace traceback: [Java] in ?"


Source: https://github.com/feldim2425/OC-Minecarts/tree/master-1.10


EDIT: Didn't open a github issue because i'm pretty sure I did something wrong.

EDIT2: After some testing I figured out, that a method in the /lib/core/boot.lua or below the loading of boot.lua in the init.lua file leads to that error. Didn't figured out what method or where.

noticed the new branch on your github. Maybe we can work together at some point, if you would accept to make/use a more flexible class which just adds the OC Integration to any entity (not limited to minecarts)

I'm working on some 1.12.2 mod with a entity as computer and already used your old oc-minecart code as reference. But specially the inventory handling looks a bit messy to me O:-)

I'm also around on IRC and you can pm me in german if you would prefer that :)
