[1.7.10] Server Commands Crash

Posted September 15, 201411 yr

Hi,

I'm trying to develop a server-side mod that add some basic command to forge basic server(without cauldron).

I don't know why but the server crash without reason, only this string:

[FML]: Fatal errors were detected during the transition from SERVER_ABOUT_TO_START to SERVER_STARTING. Loading cannot continue

Here are my classes:

Post the full crash log? That single line isn't enough to tell much. It should continue with something like

"The following problems were captured during this phase"...etc...
