Pending questions in issues

Hello Sebb, Milamber, all,
There are some questions pending in these issues:

   - 43294 <https://issues.apache.org/bugzilla/show_bug.cgi?id=43294>
   - 43539 <https://issues.apache.org/bugzilla/show_bug.cgi?id=43539>
   - 51810 <https://issues.apache.org/bugzilla/show_bug.cgi?id=51810>

Regarding 43294 <https://issues.apache.org/bugzilla/show_bug.cgi?id=43294>,
if you confirm the way I plan to fix it is ok, I can take it into account.

51810 <https://issues.apache.org/bugzilla/show_bug.cgi?id=51810> has been
closed as wontfix, I reopened it because reading
43539<https://issues.apache.org/bugzilla/show_bug.cgi?id=43539>i think
there has been a regression introduced in previous version (not
blocker for release)
It seems to me that if
51810<https://issues.apache.org/bugzilla/show_bug.cgi?id=51810>is
closed,
43539 <https://issues.apache.org/bugzilla/show_bug.cgi?id=43539>  should
also be closed.
Otherwise the fix should be to either remove the file input inherited from
parent or use it to save file.

Hope you have some time to answer
Regards
Philippe
