When running latest (1.2018.8) plantuml on a file that just contains one of the AsciiMath examples, it shows error java.lang.ClassNotFoundException: org.scilab.forge.jlatexmath.TeXFormula. I din't download the JLatexMath jars because they're not needed for AsciiMath according to the documentation. It still creates an output, but the formula is just rendered plaintext, with math syntax removed.
