difficulties building abcl 1.5 from source distribution

So far I wasn't able to build abcl release 1.5 under Linux (Ubuntu 16.04.3
which comes at this time with ant 1.9.6 and openjdk 1.8.0_131) from the 
distributed source [1]. The (ant) build completes (reportedly) successful 
even though there are errors:

Meanwhile I cloned the git repository and the HEAD as well as a branch off
of commit 3e92245341ef07dd0915d1f7f59fa335626330db (release 1.5 [a tag would
be nice, imho]) build and run successful, as far as I can tell.

I noticed that the files in the zip archive are DOS formatted, which
_shouldn't_ cause any such issue (making comparison with the files in the
git repository a bit more cumbersome though).  I haven't investigated further,
as I got now a working abcl, but wanted to have mentioned it, as I couldn't
find any hint regarding above error online.
