Javadoc: package.html or package-info.java

Question

When trying to create package level Javadoc comments, whats the preferred method? What do you do?

package-info.java

• Pros
  • Newer
• Cons
  • Abuse of a class - Classes are for code, not for only comments

package.html

• Pros
  • HTML extension means its not code
  • Syntax highlighting in IDE's/text editors
• Cons
  • None?

For me, I've always used Package.html. But I'm wondering if its the correct choice.

Answer 1

package-info.java: "This file is new in JDK 5.0, and is preferred over package.html."—javadoc - The Java API Documentation Generator

Addendum: The big difference seems to be package annotations. There's a little more in the way of rationale in 7.4 Package Declarations.

Addendum: The annotation feature is also mentioned here and here.
