In Project Annotation Proccessor

very short: Some classes are required by my annotation proccessor which when run first compiles the whole project to run which fails because of the classes that its generating missing in some other classes because they are loaded at the same time causing a chikcen egg problem. Running in different sub projects causes either a dependency loop or missing dependencies for some classes with dependencies. full explenation: I recently stumbled across annotation Proccessing and wrote one that works for my purposes as long as its in a different gradle project. However If I want to add something that utilises Classes from my main Code I need to change the location to that other class including that classes dependencies which is quite annoying. However I cant put it in the same project since parts of my code are generated using that annotation Proccessor. That means that the compilation which is needed before the processing fails since the imports to those auto generated classes fail since they are deleted on regeneration. meaning a chicken and egg problem. However the classes that use that generated code are not required by my processor. Meaning I basically would have to only compile the annotation processor first and then the classes as it needs them. After that the rest can be compiled. Question is how could I do that? any other way is also fine by me....

Unallocating direct buffer

I have a direct buffer that I eventually no longer need and set to null. This however does not free up the memory usage until I perform GC manually. Is there a way to forcefully free that memory automatically when im setting the buffer to null?...

Making an object that can be various types?

I have a byte[] and a short[] used for the same thing. I want to switch from using the byte[] and short[] based on the maximum value needed, which changes occasionally. My idea is to have an Object that is swapped between referencing the byte[] or the short[] as needed. The part I can't figure out is casting the Object to the array type its referencing. I tried this to alter the contents of the array the object is referencing: ```java...

Minecraft plugin that displays text above a player's head

I have the queue, display, and deletion working, the only issue is that there can be multiple ArmorStands/Messages at once, regardless of the fact that I have a Map associating a single armor stand with a player. When the display function is called, it checks if there is an associated armor stand, and deletes it (before i get queue working, i want there to be one message displayed at a time) ``` public final Map<Player, ArmorStand> playerArmorStand = new HashMap<>(); ...
