It is a bit annoying, but you can click the "web" link right underneath the title, which sends you to a google search of the title [1]. Clicking the WSJ result gives you a paywall bypass.
I believe this happens if you've already visited a link to the article (that's what happened to me). Try opening a private browser session, paste in the google link and click through to the article and it should bypass correctly (it worked for me!) :)
