I get a SunCertPathBuilderException when I try to load an RSS feed.

Full stack trace bellow.
I have already tried everything on https://wiki.vuze.com/w/Known_Issues#Sun...rException including switching to Beta 5.7.3.1_B10 even though the article is old and the issue should have been fixed in the 5.7.3.* stable versions already.

I also tried to uncheck "Automatically install unknow SSL certificates withou prompting", just to see what happens.

When I refresh the feed, I get a popup, see attachement. I say yes but it seems to fail and I can't load the feed.

Updating RSS Feed Scanner to 1.5 fixed my issue.
