Due to our usage of Java 7 in the beginnings of the TridentSDK project, we did not have tools accessed by the switch to Java 8. In doing so, we have unlocked a wealth of new libraries and methods to assist with the development of TridentSDK, and in particular, cache like methods such as compute, computeIfAbsent, computeIfPresent, etc...
These are simply far better implemented, most likely intrinsic and available to optimisation based on the system, and are part of the library now, making the ConcurrentCache which was meant to be a solution to backwards compatibility, now obsolete.
This class will be removed in the following updates and replaced with the proper calls to ConcurrentHashMap instead.
Thank you again for the continued support of our project.
