[1.8] Class not found exception

Posted September 10, 201510 yr

I am encountering a problem when building my mod and running it on the server.

I know that the class not found exception is occuring because the server is triing to access EntityPlayerSP, which he isnt knowing (because hes a server). But I dont know know WHERE he is acessing it.

The log seems to be in here

at de.failender.shadowsrising.ShadowsRising.init(ShadowsRising.java:127) ~[shadowsRising.class:?]

which is

 MinecraftForge.EVENT_BUS.register(new ShadowHandler());

To be honest. I have no idea.

public class ShadowHandler {
