StackOverflowError in Cable-Network

[44tim44]

Hi,
I'm trying to implement a energy-cable system in my mod.
My choice of algorithm was;
Having the cables simply forward which generator it's connected to, to the machine on the other end of the cable.

[G][C][C][C][M]
(G = Generator, C = Cable, M = Machine)

Now, I'm trying to implement a hub, which allows multiple generators to connect to one hub, which sums up the charge from the generators and sends it along its one output-side.

[G][C]
     [H][C][M]
[G][C]
(G = Generator, C = Cable, M = Machine, H = Hub)

However, I'm getting a StackOverflowError, when calculating the charge-sum in the hub.
I'm not quite sure if I've accidentally programmed a recursive method, but I don't think so, and I'm unable to find why it's happening.

All code is available at https://github.com/44tim44/BetterThanElectricity_1.12.2/tree/master/src/main/java/se/sst_55t/betterthanelectricity

The hub's TE is block/multiSocket/TileEntityMultiSocketIn

Any help is appreciated!

Nevermind, managed to solve it on my own.
My cables were referring back to the hub, so the hub got itself in its list of things to find the charge of, which resulted in a loop.
