I cannot fix this problem. This problem seems to be occurred by cause from another mod. This was caused by another mod including "incomplete" API package.
Incomplete API package is including package-info file, but lack some API class that must be included. It cause to malfunction of @optional annotation.

In this case, Any other mod include incomplete API of CoFHCore, and cause this crash. Please report author of that mod.
Or, as another solution, please use CoFHCore.
