RFR: 8331467: ImageReaderFactory can cause a ClassNotFoundException if the default FileSystemProvider is not the system-default provider

[jyxzwd]

Use the built-in file system provider rather than the custom file system provider.
Add "public static FileSystemProvider create" method in DefaultFileSystemProvider which is from java8API to be compatible against runtime.
