Why are you using ide.properties , ide.FontSize.en = 18 to set the editor/grid font? That's configurable in the preferences directly.
4.1, 4.2, and 17.2 do not honor the font size setting for links from what I can tell, although 4.1 would show the link text sans italics/underline, until you mouse over it and then it would underline. 4.2 and higher shows the link underlined and italicized.
I'm using the ide.properties to enlarge all the fonts in the application: menu titles, window titles, dialog boxes, etc. (I do see dialog boxes that don't that take this property into account since the box is sometimes too small to display the full text; i.e. cutoff text phrases.) And the 'View' menu has enough items to vertically fill my monitor! :-)
Here's the same screenshot from the 18.104.22.168 version:
You can see how the hyperlinks are significantly more readable than the 17.2 screenshot.
Ironic that I was asking about the documentation because I wondered if I could redefine a default style for the hyperlinks - without the underline and italic. And to tease me, when I double-click on the 17.2 hyperlink, the link text very briefly displays in the larger, non-italic, non-underline font! I'm suspecting that 4.2 introduced a new default style -- underline and italic -- potentially overriding the ide.properties setting.

I"m thinking that's a pretty good guess.
I think the real bug here is that the links, shown in a grid, aren't respecting the code editor font settings.
