[1.7.10]IllegalAccessError when placing down or break a TE Tesseract with EnderCore installed

[picatrix1899]

Hello again, I know this seems like a repost of a closed problem but some things have changed.

It's about the "IllegalAccessError when placing down or break a TE Tesseract" issue I've just posted at EnderIO yesterday.

When you place down or break a Tesseract from TE the game crashes.

Old Issue at EnderIO : https://github.com/SleepyTrousers/EnderIO/issues/4307

I've posted an issue at CoFH. KingLemming told me:

Caused by a mod including an invalid version of the CoFH API. Quite possibly EnderIO. You'll have to perform jar surgery.

after this I investigated further including checking sourcecodes. But I'm not really good in modding so I barly know whats going on.

The result of the investigation is that the enderIO version 2.2.8.381 does actually work I've just forgotten to remove EnderCore. But EnderCore itself causes the problem. I tested a "halfway clean" setup only with Liteloader, CoFHCore, Thermal Foundation, Thermal Expansion and EnderCore. I used very early versions and late versions of EnderCore but not one worked. I can only ask you because there is only one version of CoFHCore for 1.7.10 out there available. I would remove EnderCore from the modpack but then I have to remove WailaPlugins too.

EnderCore is a long while out there and no one ever had this problem? what am I doing wrong? And of course most important what do I do now? I can only test further.

tested versions:

• EnderCore: 1.7.10-0.2.0.39_beta
• EnderCore: 1.7.10-0.2.0.36_beta
• EnderCore: 1.7.10-0.2.0.34_beta
