My understanding of [1] is that these texts must go to the
      NOTICE
file(s).

I interpret this using the section on 'BUNDLING PERMISSIVELY-LICENSED
DEPENDENCIES'

AFAICT, adapting code from a (permissively-licenced) library is not a
"bundled dependency".

In my understanding, this pragraph applies instead:
---CUT---
Copyright notifications which have been relocated from source files
(rather than removed) must be preserved in NOTICE. However, elements
such as the copyright notifications embedded within BSD and MIT
licenses need not be duplicated in NOTICE -- it suffices to leave
those notices in their original locations.
---CUT---

I could be mistaken, but I think that the "Complex.java" source file
could not be distributed under two licences. If it were so, which one
does actually apply?



The legal docs are mainly targetted at inclusion of entire 3rd party 
works. In this case we have snippets adapted from third party works 
included into our code. So perhaps this applies [1]:


---CUT---

WHAT IS THE PROVENANCE OF SOURCE CODE FROM THE ASF?


CODE DEVELOPED ELSEWHERE, RECEIVED UNDER A CATEGORY A LICENSE, 
INCORPORATED INTO APACHE PROJECTS, DISTRIBUTED BY APACHE, AND LICENSED 
TO DOWNSTREAM USERS UNDER ITS ORIGINAL LICENSE



This code retains its external identity and is being incorporated into 
an Apache project for convenience, to avoid referencing an external 
repository whose contents are not under control of the project. The code 
retains its original license; and distribution as part of the Apache 
project explicitly calls out the license. The code retains its original 
header which refers to its own license in the distribution. If changes 
are made to the code while at Apache, the standard Apache header is 
prepended to each changed file. Additionally, any legally-required 
notices related to the code are published in the distribution.


---CUT---


So here we fall into the "If changes are made to the code while at 
Apache" section. We prepend the file with the Apache header and include 
the original license as well.



Since the original code is in a different language the source has been 
modified by necessity. I cannot find a section on software conversions.



It may be clearer to extract the relevant parts that have been adapted 
into a new source file. This can have the Apache header and then the 
original header from the original work. For the two items involved they 
can be extracted into separate files without impacting the original 
location.


I can raise this with the legal team if no-one knows any better.

[1] http://apache.org/foundation/license-faq.html#provenance





Here it states that we can add the 3rd party license within the LICENSE
file.


This page describes 'WHAT ARE REQUIRED THIRD-PARTY NOTICES?' [2]

"Apache releases should contain a copy of each license, usually
contained in the LICENSE document. For many licenses this is a
sufficient notice. For some licenses some additional notice is required.
In many cases, this will be included within the dependent artifact."


So I think that we put the 3rd party notice in LICENSE and then add to
NOTICE only if the license text has additional notice requirements. From
reading each included licence it appears to me that the LICENSE is all
that is required and the 3rd party works have no additional notice
requirement.

[2] http://apache.org/legal/resolved.html#required-third-party-notices

This is confusing indeed.
I'd tend to think that the page that specifically addresses
the contents of both "LICENCE" and "NOTICE" should be
the common ground.  [Your interpretation of it may still be
correct, of course.  Hopefully someone else can give an
opinion.]


Side-note: Files "LICENCE.txt" and "NOTICE.txt" should be renamed
(cf. NUMBERS-146).

I can do this if you like.

Sure, thanks.

Best regards,
Gilles

Best,
