The test's code differs from jdk9 as InputStream's transferTo method was 
introduced in jdk 9. I rewrite that part as:

+                try (FileInputStream fis = new FileInputStream(
+                        TEST_CLASSES + FS + file)) {
+                    byte[] buffer = new byte[1024];
+                    int read;
+                    while ((read = fis.read(buffer, 0, buffer.length)) > 0) {
+                        jos.write(buffer, 0, read);
+                    }
+                }


All the other code is identical. Tested with JPRT.

Thank you,
Svetlana
