-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.

+         * JarJar only targets Minecraft 1.18+ which is Java17+ Which means we can exploit the fact that
+         * these are Disjointed file systems, and close all unselected libraries.
+         *
+         * https://github.com/openjdk/jdk11u/blob/25a9b9e5594e88c9e1e66f95c7ca45d5a9da8854/src/jdk.zipfs/share/classes/jdk/nio/zipfs/ZipFileSystem.java#L703
+         *
+         * 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.
