+         *
+         * 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.

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.
