Deprecate RuntimeDistCleaner (#10771 )
- Logs warnings when `@OnlyIn` is used by mod devs in their own code - In a future release, only applies to MC classes during server runs - Future FG7 and installer versions may shift RuntimeDistCleaner's server effects to compile/setup/install time to completely remove the need for runtime stripping

-Minecraft Forge: Credits/Thank You
-
-Forge is a set of tools and modifications to the Minecraft base game code to assist 
-mod developers in creating new and exciting content. It has been in development for 
-several years now, but I would like to take this time thank a few people who have 
-helped it along its way.
-
-First, the people who originally created the Forge projects way back in Minecraft 
-alpha. Eloraam of RedPower, and SpaceToad of Buildcraft, without their acceptiance 
-of me taking over the project, who knows what Minecraft modding would be today.
-
-Secondly, someone who has worked with me, and developed some of the core features
-that allow modding to be as functional, and as simple as it is, cpw. For developing
-FML, which stabilized the client and server modding ecosystem. As well as the base
-loading system that allows us to modify Minecraft's code as elegently as possible.
-
-Mezz, who has stepped up as the issue and pull request manager. Helping to keep me
-sane as well as guiding the community into creating better additions to Forge.
-
-Searge, Bspks, Fesh0r, ProfMobious, and all the rest over on the MCP team {of which 
-I am a part}. For creating some of the core tools needed to make Minecraft modding 
-both possible, and as stable as can be.
-  On that note, here is some specific information of the MCP data we use:
-    * Minecraft Coder Pack (MCP) *
-      Forge Mod Loader and Minecraft Forge have permission to distribute and automatically 
-      download components of MCP and distribute MCP data files. This permission is not 
-      transitive and others wishing to redistribute the Minecraft Forge source independently
-      should seek permission of MCP or remove the MCP data files and request their users 
-      to download MCP separately.
-      
-And lastly, the countless community members who have spent time submitting bug reports, 
-pull requests, and just helping out the community in general. Thank you.

-=========================================================================
-
-This is Forge Mod Loader.
-
-You can find the source code at all times at https://github.com/MinecraftForge/MinecraftForge/tree/1.12.x/src/main/java/net/minecraftforge/fml
-
-This minecraft mod is a clean open source implementation of a mod loader for minecraft servers
-and minecraft clients.
-
-The code is authored by cpw.
-
-It began by partially implementing an API defined by the client side ModLoader, authored by Risugami.
-https://www.minecraftforum.net/topic/75440-
-This support has been dropped as of Minecraft release 1.7, as Risugami no longer maintains ModLoader.
-
-It also contains suggestions and hints and generous helpings of code from LexManos, author of MinecraftForge.
-https://minecraftforge.net/
-
-Additionally, it contains an implementation of topological sort based on that 
-published at http://keithschwarz.com/interesting/code/?dir=topological-sort
-
-It also contains code from the Maven project for performing versioned dependency
-resolution. http://maven.apache.org/
-
-It also contains a partial repackaging of the javaxdelta library from http://sourceforge.net/projects/javaxdelta/
-with credit to it's authors.
-
-Forge Mod Loader downloads components from the Minecraft Coder Pack
-(http://mcp.ocean-labs.de/index.php/Main_Page) with kind permission from the MCP team.

+         *
+         * Combined with the fact that the JarJarFileSystem has always simply called into FileSystems.newFileSystem for its wrapped targets.
+         * https://github.com/MinecraftForge/JarJar/blame/b39b2051439c81519d826d38898778bf3081356f/src/main/java/net/minecraftforge/jarjar/nio/pathfs/PathFileSystem.java#L38
+         *
+         * This effectively means that JarJar has ALWAYS been a wrapper around in-memory copies of every jar it scans.
+         *
+         * It also never closes these FileSystems, which potentially means they are leaked if the GC can't inherently GC them.
+         *
+         * Ideally we would extract these contained jars to a temp folder, so that we can use the nice optimizations Java has for ZipFile/JarFile.
+         * But in order to do that we would need to write the file to a place that could potentially have conflicts.
+         * To resolve those conflicts we should take a hint out of maven/gradle/minecraft's book and key the filepath based on a hash of the file being extracted.
+         * However, because that hash is no available in existing metadata we would need to re-calculate it.
+         *
+         * To do it in an efficient way we I needed to be able to share the single opened FileSystem with both the SecureJar implementation, and with our recursive search.
+         * So I use my new ReadOnlyInMemoryFileSystem which is specifically designed to use the same backing array for the JarInJar search as it does with the resulting dependency
+         * selected SecureJars.
+         *
+         * This means that if we wanted to we could rather efficiently calculate a hash for extracting the file. However, it also means that we don't have to extract to file to
+         * support ZipFileSystem caching properly. So as long as we are okay with not using the JRE's optimized ZipFile implementation, or we want to support legacy JarInJar metadata,
+         * using this efficient in memory file system is the best option performance wise. Extracting the files during launch without an efficient caching/unique identifier system
+         * would incur a lot of Disc IO which can be super slow depending on your setup.
+         *
+         * So, it is a stated goal of our future re-write to extract files into a cache directory to gain the benefits of JRE optimizations, using a FileSystem much simpler then
+         * the existing JarInJarFileSystem is good enough.

 to some of the data and functions you need to build a successful mod.

-Note also that the patches are built against "un-renamed" MCP source code (aka

 If at any point you are missing libraries in your IDE, or you've run into problems you can 
 run `gradlew --refresh-dependencies` to refresh the local cache. `gradlew clean` to reset everything 
 (this does not affect your code) and then start the process again.

-Mapping Names:

LexManosandPaint_Ninja	b0ccf1a480	Minecraft 1.21.9 update. There a lot of performance improvements related to events. No more InheritableEvent for abstract events that you shouldn't add listeners to anyway, like EntityEvent. Use their sub-events. Made a lot more events records and interfaces. Mostly just a binary break, but has better performance. Mod bus posting methods are now static, no more ModLoader.get() for those. ObjectHolder was removed, use RegistryObject. Changed RuntimeEnumExtender to only target Minecraft classes. If you want other modders to interact with your API, use an Interface instead of Enum. Moved some abstract event methods to only the relevant sub-events now, e.g. can no longer check the side of a ClientTickEvent, because it'll always be client Rendering has changed a lot, they now batch most things together so that the game will render faster. RenderHighlightEvent changed a lot See https://github.com/MinecraftForge/MinecraftForge-Experimental/tree/1.21.9-dev for unsquashed commits.
