Automatic cleanup on FileSystem::close could be problematic. Consider the
following code snippet:
FileSystem fs = FileSystems.newFileSystem(URI.create("jrt:/"),
Map.of("java.home", targetJavaHome));
FileSystemProvider provider = fs.provider();
fs.close(); // URLClassLoader is closed automatically now
...
FileSystem newFs = provider.newFileSystem(URI.create("jrt:/"), Map.of());
// Now any call to newFs instance that require additional class loading crashes
