java.lang.LinkageError

Hello!

Let me first explain what I'm trying to do. I have an API plugin that I want to use to make my own "APlayer" object, managed by the "APlayerManager" object. Below I've linked gists of simplified versions (removed all the getter/checker methods that aren't relevant to my question).

APlayer.java https://gist.github.com/thoosequa/847a43ea50657771cdbf
APlayerManager.java https://gist.github.com/thoosequa/c854bfb9b6b21f278cef

I get the APlayerManager by calling "API.playerManager" (which gets a static object of APlayerManager for the API).

Now - This all works fine with no errors, but when I reload the API plugin, I get this error:
Caused by: java.lang.LinkageError: com/github/thoosequa/api/aplayer/APlayer
whenever anything tries to call the "API.playerManager.getAPlayer(name)" and get an APlayer object for the player.

Any help related to this issue, or any tips/pointers on how I could improve what I'm trying to achieve are greatly welcomed

 

Here is the docs for LinkageError that may help you find an answer (never encountered this error so I am not exactly sure): http://docs.oracle.com/javase/7/docs/api/java/lang/LinkageError.html

 

Thanks for the link; I think I understand the why this error has arisen now, but I still can't think of a way to fix it. xD
