Had to create a getGameServer() method in AuthMe in order to be able to catch this call in tests and replace it with a mock implementation of the actual server. The supertype method getServer() is declared as final, which makes it impossible to mock with Mockito.
While there are frameworks that manipulate the bytecode to mock final calls, it is much easier and less risky to simply delegate the server retrieval through another method.
The HelpSyntaxHelper had suppressed warnings for string concatenation within StringBuilder - the point of the StringBuilder is that it is faster when you use it to concatenate many elements. If you still use string concatenation with + within these calls it beats the purpose.
