The files are there -- you just can't see them!  You have to loop mount them.If you do this and still can't see them, then it may be something missing inthe O/S from your upgrade.  GG is going to upgrade to 42.4 Leap real soonand I will test there too.
1) cd /<work_path>/bd_2016daytime/   !# which is /tmp/bd_201619-170858 for me
2) ls  !# you will see:
    bd.m2ts  bd.sh  bd.udfs  bd.xml  udfs
3) umount /tmp/bd_20161219-170858/udfs  !# substituting your filename
4) mount -o loop ./bd.udfs udfs/
5) ls udfs/  !# you will see:
   BDMV  lost+found
6) ls udfs/BDMV/  !# you will see:
7) cd /<work_path>8) umount /tmp/bd_20161219-170858/udfs  !# substituting your daytime filename
After bdwrite is done, the need for the BDMV file structure no longer exists asthat information is included in the bd.udfs file which is written to the disc.  Noticehow bd.udfs is larger than bd.m2ts -- it includes all of m2ts along with the 
necessary bluray structure.
BTW.  the JAR file under BDMV is the Java BD-J information that I thought yourplayer needed to automatically start playing.
PS: OSB is being evaluated.

I am thankful and excited to test it when a (preliminatry) Leap build is 

Just to add, in case this can be a clue in debugging something. I have 
sorted throug and verified my 17 test BD renderings. 5 of these have a 
udfs/BDMV structure written, on which were rendered in May 2016, between 
bd_20160506 - bd_20160516 (ws and laptop). The rest (12), mostly 
rendered later now in December, contain an empty udfs folder. In all 
cases the first bd.m2ts are rendered ok.
