 In 1.9.0 a new method `getDescrptorFile` was introduced.  This actually
 can cause various problems and has some open design questions that should
 be answered in this ticket.
 (I'll attach a branch with a test demonstration part of the problem.)

 `DescriptorParser` has the new method (since 1.9.0):

 {{{
 public Iterable<Descriptor> parseDescriptors(byte[] rawDescriptorBytes,
     File descriptorFile, String fileName);
 }}}

 In addition to the problem demonstrated in the (to be attached) test this
 raises some questions:

 1) What should be done, if `descriptorFile.getName() != fileName`?
 2) What should be done, if `descriptorFile != null && (null == fileName ||
 fileName.isEmpty())`?
 3) What should be done, if `descriptorFile == null && null != fileName`?
 4a) What should be done, if `descriptorFile == null && null != fileName &&
 fileName.isEmpty()`?
 4b) What should be done, if `descriptorFile == null && null == fileName`?
