RFR: 8374819: Some I/O streams left unclosed

[Alexey Semenyuk]

- Replace `Files.newInputStream(path)` in chain method calls with either `new ByteArrayInputStream(Files.readAllBytes(path))` or `path.toFile()` if there is an alternative method taking a `File` instance instead of an `InputStream` and if appropriate.
 - Add missing try-with-resources for `Class.getResourceAsStream()` calls.

-------------

Commit messages:
 - Close opened streams or replace DocumentBuilder.parse(InputStream) with DocumentBuilder.parse(File) whichever suits better.
