- The gclib dependency in the EnchancerFactory has been removed. All classes that used the actual factory part of it have been updated to use bytebuddy instead. This class will have to be removed at some point, but at the moment it is still used for accessing its class loader.
- Renamed EnhancerFactory to ByteBuddyFactory. All ByteBuddy actions should go through this now. Every subclass created here implements the ByteBuddyGenerated interface. This makes it possible to recognize classes generated using ByteBuddy (by default, it doesn't leave such a trace).
- Removed the method DefaultInstances#forEnhancer(Enhancer). This method isn't used anywhere; the last trace of usage of the method I could find was in 2013 (in the NetworkServerInjector). External plugins (I couldn't find any that used it), they should really have their own implementation, given that they already require an instance of an Enchancer. As such, I feel it is safe to remove rather than update it.
Added an override to the encoder as such would process any non-wire packets as NMS packets. In the case of the use of different APIs, such as Artemis Packet API, such would cause a conflict and would spit out casting exceptions. It is quite easy to resolve by exclusively accepting Wire Packets and packets which are assignable to the packet class. This solves the issue and tada happy ending.
- Implemented a fix for the incompatibility with Java 15. This incompatibility was caused by the fact that the lambda generated in the NMS.NetworkManager is a hidden class in J15. Starting in Java 15, final fields in hidden classes can no longer be modified regardless of the 'accessible' flag. (see https://openjdk.java.net/jeps/371 "Using a hidden class", point 3). To circumvent this issue, this retrieves the data from the existing fields in the hidden class (a runnable or a callable) other than the packet. It then retrieves the constructor of the hidden class and instantiates it using the previously-retrieved data and the modified packet instance (this code is only used if the packet instance changed).
- Introduced a new ObjectReconstructor class that does all the fields/constructor discovering/accessing etc. The Runnable and Callable methods each get one instance of this class so that we can avoid having to get the fields/constructors and set them accessible every time we want to replace a packet.

Note that things may not initially work as expected. There are known issues (see #880) relating to dimensions, chat packets, and tile entities. There were also internal changes to attributes, though hopefully those are fixed. As always, report issues on GitHub.
Thanks to @KennyTV and @MedicOP for their help in tracking this bug down. Essentially the decode method we were using could be different depending on when the player logged in, which clashed with PL's static handling of it.
