When a skinparam is used to set a font size in latex, this is disregarded.

Latex handles font sizing "strangely", in that usually users don't set a font other than the base fonts and then all fonts are proportions of that font.  

This test uml:

@startuml
skinparam legendFontSize 8
skinparam activityFontSize 14

:A;

legend right
        legend text
endlegend

@enduml

Renders like this in a normal render:

In latex it renders like this: https://www.overleaf.com/read/gdnstsqtjhsw - i.e. no font scaling takes place.

From this latex code:

\documentclass{standalone}
\usepackage{tikz}
\usepackage{aeguill}

It is possible to set a specific font size in latex.

In effect... if you had a node with the text 'This is some text'  you can make your node look like this: \node at (0pt,0pt)[below right,color=black]{\fontsize{8pt}{9.6pt}\selectfont{legend text}};

The first value (set above at 8pt) is the font size, the next (9.6) is a line spacing.  Line space in latex is usually 1.2 times the text size.

There is an example latex file on the same link as above (called amended) - its not perfect - the 'A' isn't centered in the node.  That could be a font choice issue. 

If we add:

\usepackage{fontspec}
  \setsansfont{Arial}
To the preamble, and then add: {\textsf } around the node - you'll get Arial as your font so can match the java font a bit easier.    Node looks like:
\node at (0pt,0pt)[below right,color=black]{{\textsf\fontsize{8pt}{9.6pt}\selectfont{legend text}}};
(Without the fontspec - you'll at least get a sans font!)
I'm not sure why A is not centering. The positioning maths is beyond me!
