Yes, this problem is still present: 

The doctree for the above example is

    <admonition classes="admonition-test">
        <title>
            test
        <paragraph>
            This is a test

i.e. it is an example of class arguments that cannot be part of a standard
latex command name mentioned in "latex.txt":

   Class arguments may contain numbers and hyphens, which need special
   treatment in LaTeX command names (see `class directive`_). The
   commands ``\csname`` and ``\endcsname`` or the special command
   ``\@namedef`` can help with the definition of corresponding macros or
   environments.

The above example should be

\expandafter\newcommand\csname DUadmonitionadmonition-test\endcsname{…}

or alternatively

\makeatletter
\@namedef{DUadmonitionadmonition-test}{…}
\makeatother

(in a package file (*.sty) you can omit the \makeat... lines).

Hope this helps,

Günter


PS: I found a typo in the latex writer documentation:
    \begincsname should be replaced by \csname
    (done in the repo).
