Current context paper size (from /usr/local/texlive/2016/texmf-dist/tex/context/user/cont-sys.rme): a4
Current dvipdfmx paper size (from /usr/local/texlive/2016/texmf-dist/dvipdfmx/dvipdfmx.cfg): a4
Current dvips paper size (from /usr/local/texlive/2016/texmf-dist/dvips/config/config.ps): a4
Current pdftex paper size (from /usr/local/texlive/2016/texmf-dist/tex/generic/tex-ini-files/pdftexconfig.tex): (undefined)
Current psutils paper size (from /usr/local/texlive/2016/texmf-dist/psutils/paper.cfg): a4
Current xdvi paper size (from /usr/local/texlive/2016/texmf-dist/xdvi/XDvi): a4


The undefined for "pdftex paper size" has an impact on Adam Maxwell's TLU which on launch issues an error message currently.
