Hi! So I'm coding a plugin and when I started my server I received the following error: https://pastebin.com/kmgdLDxm It seems like something is wrong at line 122 in my PlayerManager.java so here is the class in which the error occurs: https://pastebin.com/cxu2vNBB I read at docs.oracle.com that this error could be thrown when: the class object represents an abstract class, an interface, an array class, a primitive type, or void. the class has no nullary constructor. However I have no idea whats going wrong. Any help?
