bug#17978: 24.3; forward-paragraph broken with javadocs


From: Justine Tunney
Subject: bug#17978: 24.3; forward-paragraph broken with javadocs
Date: Wed, 9 Jul 2014 19:40:50 -0400

Assume that I have the following Java source, where # indicates the cursor position:

/**
 * Does stuff.
 *
 * <p>Hello
 *
 * @see FooBar
 */
private void lol() {}
#

So I press C-{ and this is what happens:

/**
 * Does stuff.
 *
 * <p>Hello
 *
#* @see FooBar
 */
private void lol() {}

And then I press it again:

/**
 * Does stuff.
 *
#* <p>Hello
 *
 * @see FooBar
 */
private void lol() {}

And here's what I expected to happen:

#
/**
 * Does stuff.
 *
 * <p>Hello
 *
 * @see FooBar
 */
private void lol() {}

C-{ and C-} should cycle between blank lines. But the reason why this doesn't happen in java-mode, is because Java redefines the definition of a paragraph. It sets the paragraph-start variable (among other variables) so that when I M-q to fill-paragraph, it'll work correctly *within* the Javadoc, rather than reflowing my code into a jumbled mess.

Could you just send plain text showing an example piece of code, then
a command you use on it, the end result you get and the end result you'd
like to get instead?

That's surely easier to do, and will save me the trouble of dealing with
videos which I find unbearable (you can't just look at them, you have to
additionally listen to them; if you get distracted along the way you end
up having to start over; half the time there's a technical problem; you
can't choose the speed at which you "read/view", so you have to wait
for irrelevant crap before getting to the point; it's a huge waste of
bandwidth).
