These two classes have a finalizer in Java 12, hence they are an unnecessary burden for GC. Use: - Files.newInputStream() instead of FileInputStream - Files.newBufferedReader() when we end up converting to a Writer - Files.readAllBytes() if we end up reading the stream - Files.copy() if we are copying the stream to another stream or file - Files.writeString() when we are emitting just a plain string - Files.newOutputStream() instead of FileOutputStream - Files.newBufferedReader() when we end up conerting to a Writer Signed-off-by: Robert Varga <robert.varga@pantheon.tech>
