This hasn't been an issue on our Wiki before. It is now.

From the Wiki MOS: For the possessive of singular nouns ending with just one s (sounded as /s/ or /z/), there are three practices: Apply just one of these three practices consistently within an article. If the third practice is used and there is disagreement over the pronunciation of a possessive, the choice should be discussed and then that possessive adopted consistently in an article.
 * 1) Add 's: James's house, Sam Hodges's son , Jan Hus's life , Vilnius's location , Brahms's music , Dickens's novels , Morris's works , the bus's old route.
 * 2) Add just an apostrophe: James' house, Sam Hodges' son , Jan Hus' life , Vilnius' location , Brahms' music , Dickens' novels , Morris' works , the bus' old route.
 * 3) Add either 's or just an apostrophe, according to how the possessive is pronounced:
 * Add only an apostrophe if the possessive is pronounced the same way as the non-possessive name: <span style="font-family: Georgia, 'DejaVu Serif', serif; color:#3CB371;">Sam Hodges' son, <span style="font-family: Georgia, 'DejaVu Serif', serif; color:#3CB371;">Moses' leadership ;
 * Add 's if the possessive has an additional /ɨz/ at the end: <span style="font-family: Georgia, 'DejaVu Serif', serif; color:#3CB371;">Jan Hus's life, <span style="font-family: Georgia, 'DejaVu Serif', serif; color:#3CB371;">Morris's works.
 * Some possessives have two possible pronunciations: <span style="font-family: Georgia, 'DejaVu Serif', serif; color:#3CB371;">James's house or <span style="font-family: Georgia, 'DejaVu Serif', serif; color:#3CB371;">James' house, <span style="font-family: Georgia, 'DejaVu Serif', serif; color:#3CB371;">Brahms's music or <span style="font-family: Georgia, 'DejaVu Serif', serif; color:#3CB371;">Brahms' music , <span style="font-family: Georgia, 'DejaVu Serif', serif; color:#3CB371;">Vilnius's location or <span style="font-family: Georgia, 'DejaVu Serif', serif; color:#3CB371;">Vilnius' location , <span style="font-family: Georgia, 'DejaVu Serif', serif; color:#3CB371;">Dickens's novels or <span style="font-family: Georgia, 'DejaVu Serif', serif; color:#3CB371;">Dickens' novels.

Add to all of that my college training in business communications, which taught us that practice #2 was invented by the newspapers to save space and crept into the language from there. It doesn't truly belong, and 's is always the correct choice. For this reason, I prefer practice #1 in all cases.

Obviously, we should be consistent not only within an article, but throughout our entire Wiki. So, <span style="font-family: Georgia, 'DejaVu Serif', serif; color:#3CB371;">Jules' or <span style="font-family: Georgia, 'DejaVu Serif', serif; color:#3CB371;">Jules's ?<ac_metadata title="Jules&#039; or Jules&#039;s?"> </ac_metadata>
