JDK-8277028: Use service type documentation as fallback for @provides

[hns]

This is a simple change to display the first sentence of the service type description in the "Provides" section of a module page if the @provides javadoc tag does not contain a description. This is the same we handle entries in the "Uses" section when no description is available from the @uses tag. The rationale is that it is still more useful to provide generic information about the service type than nothing if no provider-specific information is available.

Looks good.

I was not familiar with this part of JavaDoc. When comparing source and documentation of the JDK, I was somewhat surprised to discover that aside from tests, neither @uses nor @provides specifies the optional description.

Thanks for the review!

I was not familiar with this part of JavaDoc. When comparing source and documentation of the JDK, I was somewhat surprised to discover that aside from tests, neither @uses nor @provides specifies the optional description.

Well the tags are documented in the "Documentation Comment Specification for the Standard Doclet", but both @uses and @provides are used without description in a lot of code bases (including JDK). I think the reason for this is that descriptions in those tags used to be displayed in addition to the first sentence from the service documentation, which I think looked kind of wrong. See JDK-8192007 for details.
