问题
I have an swing panel with a JLabel inside of it. The JLabel looks like this:
new JLabel("<html>/Foo <br/>/Bar <br/>/Foo<br/>/Bar</html>");
However it displays in the UI like the following:
Bar
Foo
Bar
For some reason, the first line just disappears. If I take out the slash or remove the html tags, it works as expected. Is there a way to make the first line show up with the slash? The reason this even showed up is that we have JLabels which are populated by third party data. I could programatically remove the slash, but I would prefer to show it in the UI if there is a way to do it. We are using html and the BR tags in order to make sure each value is on a separate line.

I guess its a parsing problem. It works if you add the body tags:
"<html><body>/Foo <br/>/Bar <br/>/Foo<br/>/Bar</body></html>"

This is a known bug. You can find it here in the bug lists.
